Climatic Setting The coastal region of this section of Alaska is characterized by excep- tionally heavy precipitation and much overcast weather. The summer temperatures are moderate and in winter the thermometer rarely reaches 0° Fahrenheit. Snowfall is abundant and the mountains near the coast contain extensive snowfields and are the seat of the greatest glacier development in Alaska. They are the gathering grounds for the great Malaspina and Bering Eiver piedmont glaciers, in addition to numerous valley glaciers. Inland from the mountains that border the coast the climate is differ- ent. The prevailing winds from the ocean lose much of their moisture in crossing the coastal mountains; the precipitation is lighter; the sum- mers are short, sunshiny, and warm; the winters are long and cold and temperatures down to 65° below zero are not uncommon. Glaciers are abundant and of the valley type. Unfortunately, climatological records for Kennecott are incomplete. From 1910 to 1920 there are only two years during which complete monthly temperatures are recorded and one year of complete1 monthly 4 See Plate III accompanying U. S. Geol.
