The Carson–Iceberg Wilderness is a 160,000-acre protected High Sierra region in California, established in 1984 and managed within the Stanislaus and Humboldt–Toiyabe national forests. Stretching from Ebbetts Pass to Sonora Pass, it spans both sides of the Sierra crest, including headwaters of the Carson River and the North and Middle Forks of the Stanislaus River. Its alpine terrain and forests support mule deer, black bear, and rare amphibians. In Silver King Creek lives the only native population of Paiute cutthroat trout. The area also holds early overland history, with crossings near Ebbetts Pass in 1827 and Sonora Pass in 1841.
