Tahtlum Peak is a 6,567-foot-elevation (2,002 meter) mountain summit in Yakima County of Washington state.
Description
Tahtlum Peak is located east-southeast of Chinook Pass and north of Dewey Lake in the William O. Douglas Wilderness. It is part of the Cascade Range and the nearest higher neighbor is Dewey Peak, 1.61 mi (2.59 km) to the south. Precipitation runoff from Tahtlum Peak drains into the American River. Topographic relief is significant as the summit rises 1,455 feet (443 m) above Dewey Lake in less than one-half mile (0.80 km) and 2,800 feet (853 m) above American River in 1.5 miles (2.4 km). The name tahtlum derives from Chinook Jargon which means "ten." The mountain's toponym has not been officially adopted by the U.S. Board on Geographic Names, and it will remain unofficial as long as the USGS policy of not adopting new toponyms in designated wilderness areas remains in effect.
Climate
Most weather fronts originate in the Pacific Ocean, and travel east toward the Cascade Mountains. As fronts approach, they are forced upward by the peaks of the Cascade Range (orographic lift), causing them to drop their moisture in the form of rain or snowfall onto the Cascades. As a result, the west side of the North Cascades experiences high precipitation, especially during the winter months in the form of snowfall. During winter months, weather is usually cloudy, but due to high pressure systems over the Pacific Ocean that intensify during summer months, there is often little or no cloud cover during the summer.
