Tamanos Mountain is a 6,790-foot (2,070 m) summit located in Mount Rainier National Park in Pierce County of Washington state. It is part of the Cascade Range. Tamanos Mountain is situated west of Governors Ridge and northeast of the Cowlitz Chimneys, all of which can be seen from the Sunrise Historic District. The name tamanos derives from Chinook Jargon and has the meaning of guardian spirit. This landform's toponym was officially adopted by the U.S. Board on Geographic Names in 1932. Topographic relief is significant as the summit rises 3,100 feet (940 meters) above the White River in approximately 1.5 mile. The normal climbing access is from the Owyhigh Lakes Trail, and from the lakes scrambling up the south slope to the summit.

Climate

Tamanos Mountain is located in the marine west coast climate zone of western North America. Most weather fronts originating in the Pacific Ocean travel northeast 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 snow onto the Cascades. As a result, the west side of the Cascades experiences high precipitation, especially during the winter months in the form of snowfall. Because of maritime influence, snow tends to be wet and heavy, resulting in high avalanche danger. 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. Precipitation runoff from Tamanos Mountain drains into the White River.
