The Coalman Glacier (also Coleman Glacier) is a glacier located on the upper slopes of Mount Hood in the U.S. state of Oregon. It is the mountain's highest glacier ranging from about , located within the crater rim, southwest of the peak. It was named for Elija Coalman (variously spelled ''Elijah Coleman''), an early mountain guide who climbed Mount Hood 586 times.〔 citing 〕 Coalman Glacier is the second most frequently visited glacier on the mountain because it is part of the popular South Climbing route from Timberline Lodge. It lies entirely within Mount Hood Wilderness. The most well known feature of Coalman is the ''Hogsback'': a snow ridge running southwest to northeast from Crater Rock toward the summit ridge. The Bergschrund is another widely known feature where the glacier pulls away from the headwall leaving a large crevasse. In 2007, it had become large enough to cause most climbers to use another route.〔Previous noticed posted at (【引用サイトリンク】 Mount Hood Climbing Report, May 17th )〕 The glacier is a remnant of the massive glaciers that formed during the last ice age. It is historically known to change configuration dramatically, at times a gradual, smooth surface to Hot Rocks; at other times the same place has a 40 ft (12 m) ice cliff.〔 The glacier flows southwest, and is bounded on the north and east by the summit, on the northwest by the rocky crater wall known as ''Castle Crags'' (also ''Hawkins Cliffs''), on the west by ''Hot Rocks'', and on southeast by the back side of ''Steel Cliff''. ==See also== *List of glaciers in the United States 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Coalman Glacier」の詳細全文を読む スポンサード リンク
