DISTRIBUTION OF THE REDWOODS
BOTH SPECIES of Redwood are found growing natively
only in western North America. Dr. Jepson, in his Silva of California,
gives the most complete available account of their distribution.

COAST REDWOOD (Sequoia sempervirens)CALIFORNIA
AND OREGON
The Coast Redwood grows only within the summer fog
belt of California and southwestern Oregon. There are three small
groves in Oregon; the others occur along the coast of California. The
Coast Redwood reaches its greatest development in Humboldt and Del Norte
counties, California, especially on the bottom lands of Smith River and
the main Eel rivers. It has a range of 450 miles from north to south,
and an average width of 20 miles, extending in some places back as far
as 40 miles from the Pacific Ocean. Its altitudinal range is from near
sea level to about 3,000 feet elevation. The southern extension of the
Coast Redwood is found in the Santa Lucia Mountains south of Monterey.
On account of unfavorable climatic conditions in this southern
extension, the stand is thin; scattered or isolated trees are far more
common than in the north.
Throughout the range, the Coast Redwood is commonly
the dominant tree, but is usually associated on the slopes with Douglas
Fir, Lowland Fir, Coast Hemlock, and Tan Oak; on the flats or river
benches it forms pure stands, crowding out all other species. At the
heads of canyons or on the divides, the Redwoods diminish in number and
are replaced by increasing numbers of Douglas Fir, Tan Oak, and
Madrona.

The distribution of the Coast Redwood appears to be
correlated with the amount of precipitation, summer fogs, and mildness
of temperature. The main part of the Redwood belt from Marin County to
Del Norte County receives on the coast line a seasonal average of 50
inches of rain. The average is higher in the extreme north. Crescent
City in northern California often receives as much as 100 inches of
rainfall annually. Southward the average decreases rapidly, diminishing
to 25 inches at the limit of the distribution. The Redwood belt is
distinguished as a region of high rainfall in the rainy season, from
about November to April; a region of prevailing fogs in the dry season,
during the summer; and a region of slight change of temperature each day
throughout the year.
There are several important and well-known stands of
Coast Redwoods, of which the following are the best known.
The Redwood Highway.One of the finest and most
beautiful highways in America extends through great forests of Coast
Redwood from Marin County, California, to the southern edge of Oregon, a
distance of nearly 500 miles. It passes through more than 100 miles of
almost virgin Redwood forestthe finest forest in the world. Dr.
John C. Merriam, President of the Save-the-Redwoods League, writing in
The Living Past, describes the trees in the following words:
As you advance into these splendid forests, the
arches of foliage narrow above you and shade deepens into twilight.
Between close-set trunks you look through windows framed in shadow. Here
and there behind these openings in a distant aisle faint touches of sun
upon the shaft of a young tree bring out its red-brown glow. Like pillars of a
temple, the giant columns space themselves with mutual support,
producing unity and not mere symmetry. Ponderous strength, an almost
infinite variety in expression of light and shade and color, and a
perspective with marvellously changing depth, compose a scene such as
canvas has yet to receive.
But woven through this picture is an element which
eludes the imagery of art. The sense of time makes itself felt as it can
but rarely be experienced. While, through contrasts of their seemingly
fantastic architecture, ancient castles may tell us of other ages,
living trees like these connect us as by hand-touch with all the
centuries they have known. The time they represent is not merely an
unrelated, severed past; it is something upon which the present rests,
and from which living currents still seem to move.
The mysterious influence of these groves arises not
alone from magnitude, or from beauty of light filling deep spaces. It
is as if in these trees the flow of years were held in eddies, and one
could see together past and present. The element of time pervades the
forest with an influence more subtle than light, but that to the mind is
not less real.

As particularly the Redwood Highway region shows,
several organizations have bestirred themselves to preserve areas of
Coast Redwoods. The Save-the-Redwoods League has been by far the most
active and influential of them. The investment resulting from the
efforts of the League, together with that of the California State Park
Commission, involves State park lands valued at more than $6,000,000,
and these lands represent a total of approximately 40,000 acres of
Redwood forest. The policy pursued by the League (as expressed in its
annual report issued in September, 1933) is "protection of the vast
investment in Redwood Parks already established in California, so as to
preserve their naturalness, enhance their beauty, and increase their
usefulness and inspiration to nature-lovers all over the world." The
League now has approximately 5,000 members. Through its influence many
sizable gifts of money have been made for the purchase of Redwood areas
for the State.
The State of California, through its Department of
Natural Resources, Division of Parks, has coöperated with the
Save-the-Redwoods League. Under the State Park Bond Act of 1927, the
State matched private gifts of approximately $2,750,000. It has placed
foresters and naturalists in various State parks. It has made the parks
accessible and attractive to visitors. Under its direction, exhibits
have been prepared which present many valuable and interesting facts
pertaining to the Redwoods.
Among other organizations active in saving the
Redwoods the best known are the Garden Club of America, the California
Federation of Women's Clubs, and the Native Daughters of the Golden
West.
Save-the-Redwoods League Coast Redwood projects.At
least four important projects in the northern Redwoods area
have been actively furthered by the Save-the-Redwoods League. Four State
Redwood Parks represent the areas involved: the Humboldt State Redwood
Park, south of Eureka in Humboldt County; the Prairie Creek Redwoods,
north of Eureka in Humboldt County; the Del Norte Coast Redwoods, north
of Eureka in Del Norte County; and the Hiouchi Redwoods, north of
Crescent City in Del Norte County. (The Hiouchi Redwoods are referred
to in the publications of the Save-the-Redwoods League as the Mill
Creek-Smith River Redwoods.)
Humboldt State Redwood Park.The Humboldt State
Redwood Park system is the largest and most notable of the four
projects; altogether it has an area of approximately 20,000 acres.
Here, as in several others among the regions preserved for park
purposes, the visitor may see a notice explaining the policy of the
State in caring for the park areas: "This property belongs to the people
of the State of California. It was acquired because it is an area of
outstanding beauty and interest. Your cooperation is asked in
preserving it in as perfect condition as possible, not only for its
present value, but also for the education and inspiration of future
generations." There are four more or less distinct units within the
limits of the Humboldt State Redwood Park. They are the following.
Richardson Grove.This grove, near the southern
end of the park, is one of the most beautiful groves of the Redwood
Highway. During the summer months, the State maintains at the grove a
ranger-naturalist who gives daily lectures, conducts all-day hiking
trips, and plans the entertainment and educational features for the
evening campfire programs. Professor Emanuel Fritz, Councillor of the
Save-the-Redwoods League, has prepared a number of exhibits for the
park. One of these is an unusual stump of an old tree, which he has
described in one of the League's pamphlets ("The Story Told by a Fallen
Redwood"): The tree was 12 feet in diameter at breast height and was
310-320 feet high. Its life history, extending back over 1200
years, may be understood by studying its growth rings and its root
system. The stump is exceptionally instructive also in revealing the
story of the building up of a river bench. "When this tree started life,
about 700 A.D., the ground level was about 11 feet lower than it is at
present. Seven great floods occurring during the life of this
tree deposited enough silt to raise the ground level more than 11 feet.
Each time the tree was partially buried, but was able to adapt itself to
the new level by originating a new and higher root system." Among other
exhibits is a section of a tree trunk illustrating a "flatiron" type of
growth; it shows 365 growth rings on one side and 472 on the other.
There is also a section of the oldest Coast Redwood the age of which has
been accurately recorded; it is approximately 2,200 years old.
Memorial groves.Just a few miles north of the
Richardson Grove are to be found about thirty rather small groves. Many
of these have been purchased and given to the State by individuals or
organizations and set aside in honor of some person or for some special
purpose. The larger and more important of these groves are the
following.
The Franklin K. Lane Memorial Grove is about 20 miles
north of the Richardson Grove. It contains 193 acres. In 1921 the
Save-the-Redwoods League obtained this property for the State with
funds supplied by friends and admirers of Franklin K. Lane, the
League's first president and Secretary of the Interior in President
Wilson's cabinet.
The Honor Grove is a few miles north of the Lane
Memorial Grove. It has been set aside by the California State Park
Commission to provide means of honoring specifically named persons
through funds raised by relatives and friends. Certain trees or parts of
the area can be designated as memorials. The grove contains 80 acres of
beautiful Redwood forest.
The Children's Forest, of 1,384 acres, just north of
the Honor Grove and on the west bank of the South Fork of the Eel River,
is partly for memorial and partly for recreational purposes. It is an
attractive bit of woodland: ferns and sorrels grow in profusion, there
is a stretch of river bank, and there are small meadows where children
can play.
The Garden Club of America Grove is one of the most
noteworthy of the memorial groves. For several years, members of the
Garden Club of America helped materially in the Save-the-Redwoods movement.
It was in large measure because of their efforts that the Council
of Presidents of this nation-wide organization, at its convention in
Seattle, in July, 1930, voted to raise a fund for the purchase of a
Redwood grove. The fund was raised by clubs in all parts of the United
Statesevidence of the nation-wide interest in the movement to save
the Redwoods. A tract of virgin forest at Canoe Creek was bought for
$150,000, half of which was provided from the fund raised by the Garden
Club members the other half by State park bond funds. The
grove includes some of the finest specimens of Coast
Redwood known. A part of it has been set aside as a "sanctuary for
native flora." The main grove, of approximately 2,500 acres, is on the
west bank of the South Fork of the Eel River, across the river from the
highway.

The Native Daughters of the Golden West Grove is a
small but nevertheless noteworthy grove of 46 acres.
The California Federation of Women's Clubs Grove has
an area of 106 acres. Over a period of many years the California
clubwomen accumulated a fund to purchase a Redwood grove, and in 1930
they were able to buy this one. An inscription on a fallen-log marker at
the grove says: "California Federation of Women's Clubs Grove, presented
to the State of California that these trees through the coming years
shall minister to the destiny of mankind." A feature of interest in the
grove is the federation's "Hearthstone."
Bull Creek Flat.This is one of the larger areas
of the Humboldt Redwood Park territory; it contains approximately 13,000
acres. It is less than two miles off the main highway on the road west
from Dyerville. Preservation of the area was in large part made
possible through the gift of John D. Rockefeller, Jr., of $1,000,000
outright and a second $1,000,000 to match private gifts.
After the acquisition of the Bull Creek Flat area,
the president of the Save-the-Redwoods League, Dr. John C. Merriam, sent
to the members of the League a special message saying: "The purchase of
the Bull Creek area marks the most important step in the development of
the program of the Save-the-Redwoods League. This, with other
acquisitions of exceptional Redwood forest, guarantees to California
and to the nation preservation and enjoyment of the most remarkable
forest tracts known. This forest constitutes one of the greatest assets
of California and of the United States, and will have increasing value
as a spiritual influence in the life of the people of the State and of
the nation."
Among the hundreds of remarkable trees of the grove,
two are of special interest and are well known to many visitors. One of
these is the "Big Tree," which is 72 feet in circumference at the base,
16 feet 6 inches in diameter, and 345 feet tall. It contains 235,000
board feet of lumber and is one of the largest of the Coast Redwood
trees. The other, the "Flatiron Tree," which stands about a hundred
yards from the "Big Tree," shows an unusual flattening of the trunk
because at the base one side grew much more rapidly than the other. This
tree is 21 feet across the base when viewed from the east, and 6 feet
when viewed from the north; at base it is 49 feet in
circumference and 15 feet in diameter, and at breast height, 41 feet in
circumference and 13 feet in diameter.
North Dyerville Flat.The Dyerville Flat area is
usually considered in connection with the Bull Creek Flat region. They
are so near together as to constitute almost a continuous park of great
beauty and value. The Dyerville grove is on the main Redwood Highway
near Dyerville. It is a region of unusually tall trees, among which is
one that is becoming well knownthe "Founders' Tree, the World's
Tallest Known Standing Tree." This tree, which is 364 feet tall, is only
slightly taller than many of its neighbors, which range from 350 to 360
feet tall, and thus is just a "taller" tree among tall trees.
Prairie Creek Redwood Park.This park, of
approximately 6,000 acres, is valued at $1,000,000. It is in the
northern part of Humboldt County, fifty miles north of Eureka. In 1932,
the report of the Save-the-Redwoods League said of the Prairie Creek
Redwoods: "Differing widely in character from that of the Redwood
forest of southern Humboldt County with its heavy 'flats,' of virgin
Redwoods along the river bottoms, the Prairie Creek forest combines both
the 'flat' type with the 'slope' type, affording splendid examples of
both. The 'slope' timber is unusual in quality, size, and density of
stand, and the exquisite forest cover very luxuriant. Numerous varieties
of ferns, notably the great sword ferns and the delicate Lomaria, grow
in almost tropical abandon, and rhododendron, huckleberry, and other
shrubs form a veritable jungle, which, except for a few old trails here
and there, is well-nigh impenetrable. The clover-like Oxalis thickly
carpets the forest floor and in spring is richly embroidered with
patches of wild iris, purple and yellow violets, delicate white
trilliums, and Redwood lilies. In late May the deep rose rhododendron
bursts into its rich flamboyant bloom. In the midst of the woods are
many venerable Western maples, the branches and trunks of which are
entirely moss covered. The silver fir, a symmetrical and beautiful
conifer, is found here, and the young Redwoods, often springing from the
stump of a fallen parent tree, seem, in contrast with the mother-tree,
to be members of an entirely different species, so graceful and
delicate they appear beside their towering, massive elders." A short
distance from the main highway, this section has its own "Big Tree." This
tree is one of the five or six largest of the Coast Redwoods; it is 90
feet in circumference, 17 feet 7 inches in diameter, and 300 feet
tall.
Del Norte Coast Redwood Park.In the southern
end of Del Norte County, near Crescent City, and on the old
Eureka-Crescent City highway, is this park of approximately 3,000 acres.
The grove affords an interesting contrast between the forest and the
sea. The Redwoods grow on rolling slopes which rise from the ocean
coastline; the western boundary of the park extends along seven miles
of ocean shore.
Hiouchi Redwood Park.The Hiouchi Redwood Park
is referred to in the publications of the Save-the-Redwoods League as
the Mill Creek-Smith River Redwoods. The present area preserved contains
less than 200 acres, but it is in a region which contains at least
20,000 acres of beautiful Redwoods that ought to be rescued from
lumbering. The park is on the Crescent City-Grants Pass highway, about
six miles northeast of Crescent City. It is a virgin Redwood forest of
unusually big trees. In the Frank D. Stout Grove at the mouth of Mill
Creek is one of the largest Coast Redwoods.
Private parks.Although there are several
privately owned parks along the Redwood Highway, mention of only two
must suffice here. One, Coolidge Park, is a small area in the southern
section of the Coast Redwoods which has at least two trees worthy of
mentionthe Coolidge Tree, through the burned base of which a
roadway has recently been cut, and the Hendricks Tree, a very large
tree with a peculiar arrangement of the large branches, which extend
outward only a few feet from the side of the tree and then turn upward
parallel with the trunk. The other, Big Tree Park, is a small park in
Del Norte County. Among its attractions are the General Custer Tree, one
of the largest of the Coast Redwood trees, and a large fallen Redwood
log with a very large spruce tree growing on top of it.
Muir Woods National Monument.Muir Woods
National Monument is in Marin County near San Francisco Bay. It was
William Kent's gift to the nation in honor of his friend, John Muir,
notable pioneer in the National Park movement. The Monument embraces 427
acres, not all of which support a growth of Redwood. The area which
contains most of the Redwood is about a mile long and a half-mile
wide.
There are hundreds of fine trees in Muir Woods. The
largest trees are estimated to be from 700 to 1,000 years old. The
tallest tree in the Monument is 240.6 feet high. The largest diameter of
any tree at breast height is 14.6 feet. Often, the Coast Redwoods sprout
from the base of a "mother" tree, forming a circle around the base of
the parent tree. Later, the mother tree may die, leaving the
sturdy offspring to continue the race. One such circle in this area, the
Cathedral Grove, comprises 42 trees.
California State Redwood ParkBig
Basin.The California State Redwood Park is about 20 miles
northeast of Santa Cruz. It is often called "Big Basin." It has an area
of approximately 10,000 acres. Several well-known trees are in the park;
for example, the Mother Tree, which is 335 feet tall, and the Animal
Tree, on which are very large specimens of Redwood burl. The Chimney
Tree is burned out, yet still continues to grow. The Santa Clara Tree is
one of the largest of the Coast Redwoods; it is 17 feet, 9 inches in
diameter, and 240 feet in height.
Santa Cruz County Big Trees Park.The Santa Cruz
County Big Trees Park, the gift of Santa Cruz County, is a few miles
northeast of Santa Cruz. Although the park is called "Big Trees Park,"
the term "Big Trees" refers to the Coast Redwood and not the so-called
"Big Trees" of the Sierra Nevada. The Board of Supervisors of Santa Cruz
County purchased the property embracing the park in 1930. There are some
very fine trees in the park, a few of which are more than 300 feet tall;
for example, the Giant Tree, the Neck Breaker, and the Cathedral group.
This grove has been visited by Theodore Roosevelt and many other
proponents of conservation.
SIERRA REDWOOD (Sequoia
gigantea)CALIFORNIA
The Sierra Redwoods grow natively only in California.
They are found on the western slope of the Sierra Nevada at elevations
ordinarily between 5,000 and 8,000 feet. Some trees have been found as
low as 3,000 feet elevation and a few grow at an elevation of 8,400
feet. They occur on favorable or protected spots where the soil is deep,
rich, and moist, and thrive in a region where the average annual
rainfall is from 45 to 60 inches. Much of this precipitation is in the form
of snow, which frequently lies from 10 to 12 feet deep and stays on the
ground for from three to six months in the year. The temperature in
winter often falls to zero or below.
The Sierra Redwoods rarely grow in pure stands, but
are found in association with White Fir, Incense Cedar, Yellow Pine, and
Sugar Pine. Of these four trees, the White Fir is the most abundant. The
Sierra Redwoods form separate and distinct groves, which are found from
west of Lake Tahoe in Placer County to the southern end of the
Sierra Nevada in Tulare County, a range of about 250
miles from north to south. In the grove west of Tahoe, there are only
six standing trees and no reproduction is being made. The number of
groves has been variously listed by different authorities at from 25 to
70.
Nearly all the more important groves of Sierra
Redwood are in National Parks, National Forests, or in Calaveras State
Park. Sequoia, General Grant, and Yosemite National Parks represent the
Government's attempt to preserve these giant trees for the enjoyment of
all America and the world.
Sequoia National Parkhome of thousands of
Sierra Redwood. Although many values are conserved in Sequoia
National Park, its chief glory is the Sierra Redwood trees and their
associates. There are more Sierra Redwoods growing in this park, and
near it, than in all the rest of the world. It is a marvelous place for
observing these trees in all their varying moods. Many of them may be
seen from the park highway, but the visitor should stop and study them
more closely; he will find no better place to do so. He may have
supposed that Sierra Redwoods grow only along mountain ridges and in
canyons; here he will see them growing also in flowering meadows and
beside rippling streams. He should take time to see their towering tops
above the smaller pines and firs as he stands at the summit of Moro
Rock. He should go to the beginning of the trail in Crescent Meadow and
walk slowly through the forest. He should gaze long at the mighty
"President Tree" and the giants of the "Senate" and "House" groups on either
hand. He should take time among them to gain some feeling of their
vitality, their majesty, their patience, and their beauty. He will find
this park a good place, besides, for learning something about the
collection of mature seeds and their storage and planting. A
well-equipped nursery is maintained, where seeds are planted for use in the
park. When the seedlings are strong and vigorous enough to withstand
the competition of the forest, they are transplanted; many places
formerly desolate have thus been made attractive.
In Sequoia National Park are more than twenty groves
of Sierra Redwood and they contain thousands of trees more than 10 feet
in diameter and other thousands of young trees. At least three of these
grovesthe Giant Forest, Muir Grove, and the Redwood Meadow
Grovedeserve special mention here.
Giant Forest.The Giant Forest, discovered by
Hale Tharp and named by John Muir, is the finest and largest grove of
Sierra Redwood in existence. It lies between the Middle and
Marble forks of the Kaweah River, and contains more than 3,500 trees
that are over 10 feet in diameter. These form, really, scores of
separate groves merging into one another. The Congress group and the
group of the Presidents are two of the best known in this forest. The
General Sherman, one of the world's most famous trees, is in this
grove.

Muir Grove.Muir Grove was named in honor of
John Muir, writer, explorer, and nature-lover, who did so much to arouse
the nation to the value of preserving the Redwoods to be enjoyed and
revered by thousands who visit them each year. The grove is almost a
forest of very large trees of almost pure stand, and is considered to be
nearly equal to the Giant Forest in interest and beauty. The grove is
situated on the North Fork of the Kaweah River watershed.
Redwood Meadow Grove.The Redwood Meadow Grove,
in the central part of Sequoia National Park, is a beautiful grove of
about 150 large trees, in which there is extremely heavy and uniform
reproduction. The grove is of especial interest because it was the gift
of Stephen T. Mather, the first Director of National Parks. Mr. Mather
did much to establish the high type of administration that
characterizes the National Parks of America.
Yosemite National Parkhome of El Capitan and
Big Trees.In Yosemite National Park are two small groves and one
that is large and well known. The Tuolumne Grove on the Big Oak Flat
road contains about 25 large trees. One of the dead trees is still
standing and a roadway has been cut through its base. The Merced Grove,
containing about 20 large trees, is on the old Coulterville road. The
tallest tree in Yosemite is one of these and is 300 feet high. The
largest and by far the best known grove of Yosemite Park is the Mariposa
Grove.
Mariposa Grovehome of Grizzly Giant and
Wawona.Mariposa Grove is situated near the southern boundary of
Yosemite National Park, about 37 miles from Yosemite Valley by way of
the new tunnel. This grove, too, is exceptionally lovely, containing
about 200 Sierra Redwood trees that are more than 10 feet in diameter.
There are hundreds of slenderer young trees. More than 10,000 seedlings
were counted in the spring of 1935. Nearly all the larger trees can be
seen from the highway, which extends past the fallen Massachusetts Tree,
the Telescope Tree, and through the Wawona or Tunnel Tree.
The Grizzly Giant, one of the oldest and largest
trees in the world, has been one of the chief attractions of this grove
for years. Its tremendous trunk, twisted and gnarled branches, and its
appearance of having withstood numerous storms and fires, give it a
distinction all its own. One large limb, 6 feet in diameter, is more
than 100 feet from the ground. Although, through the centuries, about
four-fifths of the bark has been burned from the base of the tree, it
still continues to live and grow.

The spirit of reverence and humility which one feels
as one enters the upper grove is intensified as one stops near the
museum to read these words written by Superintendent Thomson:
These
Sequoia gigantea are of a noble lineage that bridges humanity back
through eons to the age of reptiles.
Here live venerable forest kings in reveries that
carry back a thousand years before Jesus Christ walked the shores of
Galilee.
In their majestic shadow, fretting men may well pause
to ponder valuesto consider the ironic limitations of threescore
years and ten.
Here, through a compelling humility, men may achieve
a finer integrity of soul.
The question most often asked of the
ranger-naturalist at the Mariposa Grove museum is, "Where is the tree
you can drive through?" This tree, which is 231 feet tall and 26 feet
in diameter, is the Wawona Tree, sometimes called the Tunnel Tree. It
was in 1880 that a roadway large enough to permit the passage of a
vehicle was cut through the tree. The Wawona is probably the most
photographed tree in the world. Pictures of the tree have appeared in
geographies for more than fifty years.
Web Edition Note: The tree fell during the winter of 1968-69.
One of the most picturesque groups of trees in the
upper grove is the group of four trees of similar size arranged in
military formation which gives them the appearance of sentinels of the
forest. They are to be seen near the museum and are known as the Four
Guardsmen. Among other important trees in the upper grove is the
Lafayette, 273 feet tall and 29 feet in diameter. The ranger-naturalist
often asks people to take hold of hands, and, with outstretched arms, to
circle the tree. It requires at least twenty people to surround it thus.
The Columbia Tree is the tallest tree in the grove; it is 285 feet in
height and 28 feet in diameter. The Mariposa Tree is 249 feet tall and
25 feet in diameter. The Washington Tree is 30 feet in diameter. These
are three of the largest and best-known trees of the Mariposa Grove.
The Corridor, Clothespin, Haverford, and Telescope
trees are fine examples of how seriously Sierra Redwood trees may
suffer from fire and yet continue to live. Fire has destroyed the
entire inside of the Telescope Tree, as well as part of both sides and the
top; it thus forms a telescope through which one may look up and see
blue sky above. In spite of these burns, it is a live, growing tree. It
is certain that it has lived without its heartwood for more than 70
years, as there have been no serious fires in the Mariposa Grove since
1862.
Several well-known trees in the Mariposa Grove have
fallen. Since the Redwoods are not killed by insects or decay, and since
fire seldom completely kills one of them, the question is often asked,
"Why do the trees fall?" Fire may burn the base of the tree so badly
that the tree becomes overbalanced and finally falls in a storm, or
after it; erosion of soil from the base of a tree may almost expose the
shallow roots, and ultimately cause the destruction of the tree; and
trees which grow near streams often lose their balance on account of
softening of the soil near the shallow roots. Almost all the fallen
trees in Mariposa Grove are down from one or more of these causes.
The Fallen Monarch, a giant which was down when the
grove was discovered in 1857, lies in the lower grove. It is an
unusually large tree, and in spite of the fact that it has been dead for
more than 80 years it shows very few signs of decay. It is often
pictured with a troop of the Sixth Cavalry grouped upon and in front of
the tree. Another famous old picture shows on the fallen trunk a
stagecoach filled with passengers and drawn by six horses.
The Massachusetts Tree is valuable in the lessons it
continues to teach, though it fell in 1927. The tree was 28 feet in
diameter and 280 feet tall. It had been badly burned before the
discovery of Mariposa Grove. Weakened by fire and adversely affected by
the highway which ran near its base, it fell in a storm in the spring of
1927. The brittleness of the Sierra Redwood is shown by this tree; it
broke transversely at a height of 75 feet from the ground, split
longitudinally in half for some distance above that point, and, yet
higher, even broke in fourths. The broken ends of the tree are covered
with a dark substance which gives them the appearance of having been
covered with creosote. This substance is rich in tannin and other
chemicals with which nature protects both the live and the dead tree
from the effects of fungi and insects. Limbs of the tree more than 5
feet in diameter are to be observed more than 150 feet from the base of
the tree.
In the summer of 1934, after a violent windstorm, the
Stable Tree fell. This tree had been used in times past as a stable;
several horses could be tied in the burned-out base of it.
The Utah Tree, near the Mariposa Grove museum, fell
in the winter of 1934-35. Severe fire scars had weakened it, and
the winter storms ended its life.
