Explore Carson Iceberg Wilderness

Explore Like a Marine!

Once the former mountain warfare training grounds of the U.S. Marine Corps, the Carson-Iceberg Wilderness as well as the Carson River draw their names from Kit Carson, one of America’s early western frontiersman. Following his initiative and boldness the first group of emigrants from the East crossed the Sierra in 1841 just north of Sonora Pass.

Inhabited most recently by the Miwok Indians but for over 10,000 years by other native groups, the Carson-Iceberg, has supported human life for thousands of years. 

Designated wilderness in 1984 and managed today by both the Toiyabe and Stanislaus National Forests, the Carson-Iceberg includes both eastern and western slopes of the Sierra in its 161,181 acres. Though it lacks modern-day glaciers, the effect of glaciation is clear on its “Iceberg” namesake, a distinctive rock formation near Clark Fork Road on the wilderness’s southern boundary. The area is also characterized by a geologic anomaly – a series of volcanic peaks and ridges known as the Dardenelles.

Glacial carved river valleys are prevalent in the Carson Iceberg wilderness but lakes a limited. Compared to the Desolation wilderness to the North, Carson Iceberg Wilderness is far less visited by tourist traffic and backpackers, hikers and horseman can find a quiet day in the wilderness in almost every corner.


Editors Choice - Carson Iceberg Wilderness Adventure

Congress designated the Carson-Iceberg Wilderness in 1984. Most of the area still includes cattle grazing allotments, and you will likely encounter cows or their signs from July to September. The Pacific Crest National Scenic Trail runs for over 26 miles within the Carson-Iceberg. About 200 total miles of foot and horse trails give access to this outstanding wilderness, where human use is moderate, especially on the eastern side.

The following regulations are necessary to assure that future generations will find the
Wilderness at least as wild and free as it is for your visit. Violation of any of these regulations could result in a substantial penalty. Official
orders authorizing enforcement are available for review in Forest and District offices. Wilderness visitors must possess a valid permit for overnight trips.
Do not camp, travel or gather in groups exceeding 15 persons. (Limit per group is 12 persons in the Mokelumne Wilderness. Voluntary reduction of group size when traveling in wilderness areas is always encouraged as a hedge against resource damage.)
