RECONNAISSANCE IN NORTHERN ALASKA IN 1901. 



METEOROLOGIC RECORD FOR 1901, BY W. J. PETERS. 



Snow was found to average about 6 feet deep in the Koyukuk Valley in April, 

 and as the preliminary expeditions ascended the north tributaries flowing from the 

 Endicott Mountains in April the depth was found to decrease until the grasses were 

 visible in the floor of the passes. By June this deep snow had practically disap- 

 peared from the lowlands. Natives report that north winds blow through the passes 

 of the Endicott Mountains with great force in winter, during which season it is 

 dangerous to travel. It is not only dangerous to face the wind, but there is risk of 

 the sled being broken by its being blown against projections in the smooth ice. 

 Fogs were found on the pass in April and dense haze in July. In both cases this 

 seems to have been blown in from the coast. 



The following table, showing the temperatures at Uglaamie, 9 miles from Point 

 Barrow, is taken from the report of the Ray expedition, 1881-1883:
