[Beckey, Fred W. Cascade Alpine Guide, Climbing and High Routes. Seattle, WA: Mountaineers Books, 2008.] 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.
Because of
maritime influence, snow tends to be wet and heavy, resulting in
avalanche danger.
Geology
The history of the formation of the Cascade Mountains dates back millions of years ago to the late
Eocene Epoch.
During the
Pleistocene period dating back over two million years ago, glaciation advancing and retreating repeatedly scoured the landscape leaving deposits of rock debris.
[ 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.][ The U-shaped cross section of the river valleys is 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.
