The Issaquah Alps are the unofficial name for the highlands near Issaquah , a suburb of Seattle , which include Cougar Mountain , Squak Mountain , Tiger Mountain , Taylor Mountain, Rattlesnake Ridge , Rattlesnake Mountain, and Grand Ridge belong. The term was introduced in 1977 by Harvey Manning, a well-known author of hiking and climbing guides, on the pages of his hiking guide Footsore 1 ; He raised their status from unnamed mountain foothills to "Alps" in order to stand up for their protection. Manning himself lived in a developed area of ​​Cougar Mountain in his “200 meter hut”.

history

In 1979 Harvey Manning supported the founding of the Issaquah Alps Trails Club (IATC) to maintain the hiking trails and to bring the Issaquaah Alps into public ownership. The IATC, which is based in Issaquah (the city is also nicknamed "Trailhead City"), often leads guided hikes through all parts of the Alps.

geography

The Issaquah Alps follow Interstate 90 from the shores of Lake Washington almost to the western flank of the Cascade Range . The mountains are made up of andesitic volcanic rock, which sits on top of older, tightly folded rocks of the coastal plain of the North Cascadian subcontinent, which united with today's Washington about 50 million years ago when the entire North American continent moved westward through the ocean. The Alps were severely eroded by glaciers during the last Ice Age . The Vashon lobe of the Cordillera Ice Sheet formed the Rattlesnake Ridge, the steep east and west flanks of Squak Mountain and deposited a huge erratic boulder on Cougar Mountain, the “Fantastic Erratic”.

Cedar Butte rises abruptly from the moraine between Rattlesnake Ridge and the actual front of the Cascade Range. Occasionally mistaken for part of the Issaquah Alps, it is a relatively young symmetrical volcanic cone and therefore more related to Mount Washington to the east than to most of the old, weathered hills of the Alps.
