Donner Pass is a 7,056-foot-high (2,151 m) mountain pass in the northern Sierra Nevada, above Donner Lake and Donner Memorial State Park about 9 miles (14 km) west of Truckee, California. Like the Sierra Nevada themselves, the pass has a steep approach from the east and a gradual approach from the west. The pass has been used by the California Trail, First transcontinental railroad, Overland Route, Lincoln Highway and Victory Highway (both later U.S. Route 40 and still later Donner Pass Road), as well as indirectly by Interstate 80. The pass gets its name from the ill-fated Donner Party who overwintered there in 1846. Today the area is home to a thriving recreational community with several alpine lakes and ski resorts (Donner Ski Ranch, Boreal, and Sugar Bowl). The permanent communities in the area include Kingvale and Soda Springs, as well as the larger community below the pass surrounding Donner Lake.

Donner Ski Ranch is a budget-oriented, family owned ski area located on Donner Summit in the Tahoe National Forest of Nevada County, California. It is owned by Janet and Marshall Tuttle, who purchased it after it went into bankruptcy. The area it is on has been used for skiing since 1937. It has ski lifts on both sides of Donner Summit, and is located close to Sugar Bowl Ski Resort. 25% of its terrain is beginner, 50% intermediate, and 25% advanced, but of the 52 runs 16 are of beginning difficulty, 20 are intermediate, and 16 are advanced. The rustic lodge, built-in 1947, is mostly made of wood, and has open pipes. Norm Sayler began working for Donner Ski Ranch in 1958, helping to build the ski area’s first chairlift in 1955. Sayler took over the management of the resort in 1958, and ran it for the next 46 years, while slowly acquiring most of the ownership. The rustic lodge was renovated after its acquisition by its current owners. At the time of the acquisition, all of the ski lifts were painted as well.
