Inner Constance is located in the eastern portion of the Olympic Mountains. This location results in less precipitation than Mount Olympus and the western Olympics receive. Inner Constance is located in the marine west coast climate zone of western North America.
Most weather fronts originate in the Pacific Ocean, and travel northeast toward the Olympic Mountains. As fronts approach, they are forced upward by the peaks of the Olympic Range, causing them to drop their moisture in the form of rain or snowfall (Orographic lift). As a result, the Olympics experience 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. Because of maritime influence, snow tends to be wet and heavy, resulting in high avalanche danger.
Geology
The Olympic Mountains are composed of obductedclastic wedge material and oceanic crust, primarily Eocenesandstone, turbidite, and basaltic oceanic crust.[2] The mountains were sculpted during the Pleistocene era by erosion and glaciers advancing and retreating multiple times.
