Mount Henderson is a 6,003-foot-elevation (1,830-meter) mountain summit located in the Olympic Mountains, in Mason County of Washington state, United States.[4] It is situated on the shared boundary of Olympic National Park with Mount Skokomish Wilderness. Its nearest higher neighbor is Mount Skokomish, 0.91 mi (1.46 km) to the east-northeast.[1] Precipitation runoff from the mountain drains into the Hamma Hamma River and Skokomish River. The mountain's toponym honors Louis Forniquet Henderson (1853-1942), a pioneering botanist and mountaineer who accompanied Lieutenant O'Neil on his 1890 expedition into the Olympic Mountains.[5]

Climate
editMount Henderson is located in the marine west coast climate zone of western North America.[6] Weather fronts originating in the Pacific Ocean travel northeast toward the Olympic Mountains. As fronts approach, they are forced upward by the peaks (orographic lift), causing them to drop their moisture in the form of rain or snow. As a result, the Olympics experience high precipitation, especially during the winter months in the form of snowfall.[7] Because of maritime influence, snow tends to be wet and heavy, resulting in 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.[7]
Geology
editThe Olympic Mountains are composed of obducted clastic wedge material and oceanic crust, primarily Eocene sandstone, turbidite, and basaltic oceanic crust.[8] The mountains were sculpted during the Pleistocene era by erosion and glaciers advancing and retreating multiple times.
