Timberline is known for its summer skiing and beautiful, historic lodge. Timberline was the continent's first ski area to offer lift-served summer skiing, and now more than 50,000 skiers come each summer. The Palmer Snowfield, at 8,500 feet above sea level, has a steady pitch at the advanced-intermediate level. It's challenging enough that you'll find World Cup ski racers from several countries practicing technique. A high-speed quad, Palmer Express, allows Timberline to keep the terrain open nearly the entire year, and gives the area the greatest vertical drop in the Northwest-3,590 feet. The deep snows of winter sometimes require cat drivers to dig out the lift, the upper terminal of which is inside the mountain. Spring skiing is incredible off this lift. Palmer runs through Labor Day every year, conditions permitting (and they usually do).Half of Timberline skiing is still below treeline and the main lodge, but few experiences in the skiing world match a ride up the Magic Mile Super Express and the Palmer Express to the top of the Palmer Snowfield. The original Magic Mile lift was the second ski lift in the country, after Sun Valley's. Silcox Hut, which served as the original top terminus and warming hut, has been restored and is open to overnight groups. Below the Timberline Lodge are many blues and greens, with a few short blacks. The trail system between the trees makes each run feel like a wilderness excursion.
