METEOROLOGICAL DATA

Snow at Grand Canyon on June 6 is something worth noting. On that date the ground on both North and South Rims was white for a short while. Although snow storms are not uncommon here in May, there are very few records of their occurrence in June.

An effect of the great drought which has prevailed throughout the country is clearly visible in the present size of the Colorado River. At this date, July 13, the discharge in second-feet as recorded at the U. S. Geological Survey Gauging Station at Bright Angel Creek is only 2,310. For comparison with this, figures showing the discharge during four other years on July 13 and also at the lowest stage of each year have been selected at random from data available -
