Jacumba Wilderness

On the eastern flank of California's coastal peninsular ranges, the Jacumba Mountains often appear as a fantastic jumble of granitic rock pushed up by faults in long-gone days. The mountains extend into Mexico, and the southern boundary of the Wilderness is the international border. A broad range, the Jacumbas are really a series of almost parallel ridges separating valleys, with each ridge successively lower than the next, forming a great staircase descending eastward into the Colorado Desert. Four transitional zones lie within the Wilderness. The western portion, the region near Smugglers Cave, provides homes for mule deer, rare peninsular bighorn sheep, golden eagles, and kangaroo rats.
