Geological Survey Bulletin 104 The Glaciation of the Yellowstone Valley North of the Park

YELLOWSTONE NATIONAL PARK DIVISION,     
Washington, D. C., May 18, 1892.

SIR: I have the honor to transmit herewith a paper by Mr. Walter H. Weed, entitled "The Glaciation of the Yellowstone Valley north of the Park."

During glacial times the broad elevated region of the Yellowstone Park was deeply covered by ice, sending out its glaciers both to the north and south. The northern glacier, after emerging from the park, entered the broad valley below, near the junction of the Gardiner and Yellowstone rivers. In the present paper Mr. Weed presents the results of his investigations of the glacial phenomena of the valley. It is a valuable contribution to glacial geology, and, so far as I am aware, is the first detailed study of such phenomena in an inclosed mountain valley in the Rocky mountains.

I take pleasure in recommending Mr. Weed's paper for publication as a bulletin of the U. S. Geological Survey.

Yours, very respectfully,

ARNOLD HAGUE,     
Geologist in charge.

Hon. J. W. POWELL,
     Director U. S. Geological Survey.
