The whole coast from Sitka to the peninsula of Alaska seems to have the same continuous climate, whether in temperature or moisture. The island of Kadiak and the recess of Cook’s Inlet are outside this climatic curve, so as to be comparatively dry. Langsdorff reports winters “frequently so mild in the low parts of Kadiak that the snow does not lie upon the ground for any length of time, nor is anything like severe cold felt.”[93] Belcher, on his passage between Montague and Hinchinbrook Islands, found an “oppressively hot sun.”[94] The Aleutian Islands, further west, are somewhat colder than Sitka, although the difference is not great. The summer temperature is seldom above 66°; the winter temperature is more seldom as low as 2° below zero. The snow falls about the beginning of October, and is seen sometimes as late as the end of April; but it does not remain long on the surface. The mean temperature of Oonalaska is about 40°. Chamisso found the temperature of spring-water at the beginning of the year 38.50°. There are years when it rains on this island the whole winter. The fogs prevail from April till the middle of July, when for the time they are driven further north. The islands northward toward Behring Strait are proportionately colder; but I remind you that the American coast is milder than the opposite coast of Asia. From Mr. Bannister I have an authentic statement with regard to the temperature north of the Aleutians, as observed by himself in the autumn of 1865 and the months following. Even here the winter does not seem so terrible as is sometimes imagined. During most of the time, work could be done with comfort in the open air. Only when it stormed the men were kept within doors. In transporting supplies from St. Michael’s to Nulato, a distance of two hundred and fifty miles, they found no hardship, even when obliged to bivouac in the open air.
