The Carson Iceberg Wilderness is located about half way between Lake Tahoe & Yosemite. The geology of the area is different than most areas in the Sierras, having a volcanic past that has created a terrain that is much different that other areas. While there are areas of granite rock in the wilderness, most of the area is volcanic rock. This has created an area with more vegetation. One downside is that many of the creeks here are located in small gorges, making it hard to get water. Sometimes it is necessary to camp near creek crossing in order to get water. The upside to camping here, is that there aren't the crowds that you would see elsewhere, just watch out for the cows.
