Mount Jefferson Panorama

This panoramic view shows Mt. Jefferson and the surrounding ramparts of Park Ridge. This image also shows the Cascade Range "rain shadow" in action. The heavy clouds to the west (right) have condensed as moist Pacific air presses against the high peaks. As the clouds pass over the range, moisture precipitates out as snow and rain, and the clouds quickly evaporate as they pass to the east (left in this view) of the range, creating the rain shadow effect. While rainfall amounts on the west side of the range can reach as high as 200 inches per year, the rain shadow creates a desert to the east, where rainfall is just 10 or 12 inches per year. This rainfall gradient can occur in the span of just a few miles.
