Draining the 10,000- and 11,000-foot peaks of this eastern high country are the three forks of the Whitewater River, tumbling streams that through the ages have carved deep, V-shaped gorges from the high mountains down into arid Coachella Valley, where the spent waters sink into the desert sands and the river becomes a broad, gravelly wash. This lower part of the river is the Whitewater known to most people, drab and unimpressive. But the high Whitewater reveals a different character; it is a rugged, isolated wilderness, even today seldom trod by man. Here dwell Nelson bighorn sheep, the largest herds of these noble animals in the San Bernardino Mountains."
