Physiographically, they are a section of the larger Pacific Border province, which in turn are part of the larger Pacific Mountain System physiographic division. The Coast Range creates a rain shadow effect by forcing moisture laden clouds to rise by expelling moisture. Hood Ski Bowl: 3500: Timberline … [1] By the Early Oligocene period c. 30 million years ago the current coastline was in place and erosion has continued to shape the range. The range creates a rain shadow effect for the Willamette Valley that lies to the east of the mountains, creating a more stable climate and significantly less rain than the coastal region of the state.

[2] Annual precipitation differs from 60 inches (1,500 mm) in some parts to up to 120 inches (3,000 mm), with the higher amounts coming in the higher elevations.
