Mount Rose, Mountain peak in Washoe County, Nevada.

Mount Rose is the highest mountain in Washoe County, in the Carson Range of the Humboldt-Toiyabe National Forest. The extinct volcano rises to 3,285 metres between Lake Tahoe and Reno, and State Route 431 crosses its summit southeast of the peak. Snow falls from November to April, and the summit looks east over the Truckee Meadows.

A weather observatory was established here in 1905 and became one of the first high-altitude stations of its kind in America. This station gathered climate data that helped scientists understand mountain weather patterns.

The name has two competing explanations: one credits early settler Jacob S. Rose, the other Rose Hickman, a friend of Washoe City newspaper editor H.S. Ham. Skiing began on the slopes around 1930, and after World War II Sky Tavern opened; the separate areas later merged into today's Mt. Rose Ski Tahoe resort.

The best time to visit is from June through September when trails are snow-free and weather is more stable. Multiple trailheads with parking exist, though winter conditions can make access difficult or dangerous.

The peak frequently experiences freezing temperatures even during summer months, creating one of Nevada's few subarctic environments. This harsh condition shapes the specialized plants and animals found here.
