Kasaan Peninsula : ウィキペディア英語版 | Kasaan Peninsula
Kasaan Peninsula lies between Clarence Strait and Kasaan Bay in the U.S. state of Alaska. It forms a cut out from the eastern coast of Prince of Wales Island on the south, and by Tolstoi Bay and Thome Bay on the north. A low mountain range forms the backbone of the peninsula, with altitudes ranging from . The southern and western shore line is abrupt and almost unbroken, and has practically no shelter from southeasterly storms which sweep up Kasaan Bay. The northeastern coast of the peninsula also rises abruptly from the water, but is broken by a number of indentations, some of which form small harbors. The first discovery of copper deposits in the Ketchikan district was made by the Russians on the southern side of Kasaan Peninsula. Kasaan is the largest settlement on the peninsula. ==Topography== Kasaan Peninsula is a promontory on the east side of Prince of Wales Island that includes about square miles. From Clarence Strait, it appears to be an island whose summits are highest near its central part and diminish in height toward the north and south. A neck of low land between the head of Kasaan Bay and the south end of Thorne Bay connects the peninsula with Prince of Wales Island. This low pass appears to represent the continuation of a valley, from wide, which is tributary to the north branch of Thorne Bay and extends northwestward through the center of Prince of Wales Island. Kasaan Bay occupies the south end of this valley. In the northward extension of this valley and on the low pass south of Thorne Bay, there are many small lakes and morainal deposits. The highest point on the peninsula is the top of Kasaan Mountain, which has an altitude of . The other mountains average about in height and their slopes are deeply dissected by small valleys and by narrow steep-sided gulches.
