While significant portions of the William O. Douglas Wilderness are high elevation forest, the overall topography is varied. The Cougar Lakes portion is characterized by high alpine lakes, and the Tumac Plateau, in a forest setting, is dotted with numerous lakes. The eastern edges of this wilderness drop to mid-elevation pine forest and bare ridges. The Meeks Table Natural research area, located on a basalt table mountain, is within this wilderness at its eastern boundary.
Climate - Climate on the Gifford Pinchot changes drastically with elevation. The area receives a high amount of precipitation. Much of the precipitation comes from October to April in the form of rain at the low elevations and as wet heavy snow in the higher elevations. Deep winter snowpacks accumulate in the high elevations.
Although snow is possible in the lowest elevations, it is infrequent. Late spring, summer and early autumn tend to bring clear, sunny days with moderate temperatures.
The William O. Douglas Wilderness is located between the White Pass and Chinook Pass highways. It can be accessed via Forest Routes 4510, 1809, 395, and 1800.
