Copper Mountain (Mason County, Washington)
Climate
Copper Mountain is located in the marine west coast climate zone of western North America. 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. 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. The months April through October offer the most favorable weather for climbing or viewing.
Etymology
The mountain was named on July 7, 1890, by Lieutenant Joseph P. O'Neil (1863–1938), United States Army officer who led the 1885 and 1890 O'Neil Expeditions to explore the interior of the Olympic Mountains. Earlier that same year, prospectors had discovered copper ore on the mountain.
Geology
The Olympic Mountains are composed of obducted clastic wedge material and oceanic crust, primarily Eocene sandstone, turbidite, and basaltic oceanic crust. The mountains were sculpted during the Pleistocene era by erosion and glaciers advancing and retreating multiple times.
