Little Comrade (Washington)

Little Comrade is located in the marine west coast climate zone of western North America.[2] Most weather fronts originate in the Pacific Ocean, and travel northeast toward the Cascade Mountains. As fronts approach, they are forced upward by the peaks of the Cascade Range, causing them to drop their moisture in the form of rain or snowfall onto the Cascades (Orographic lift). As a result, the west side of the 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.[3] Because of maritime influence, snow tends to be wet and heavy, resulting in high avalanche danger.[3]

The history of the formation of the Cascade Mountains dates back millions of years ago to the late Eocene Epoch.[4] During the Pleistocene period dating back over two million years ago, glaciation advancing and retreating repeatedly scoured the landscape leaving deposits of rock debris.[4] The last glacial retreat in the area began about 14,000 years ago and was north of the Canada–US border by 10,000 years ago.[4] The U-shaped cross section of the river valleys are a result of that recent glaciation. Uplift and faulting in combination with glaciation have been the dominant processes which have created the tall peaks and deep valleys of the Cascade Range.
