Upstream from Moab on the Colorado River, near the Colorado state line, there is a relatively short, deep canyon that has become one of the most popular river-running destinations in America. The canyon is known as Westwater. Its popularity is largely due to the thrill provided by one of the most dangerous and challenging stretches of white water on the Colorado---Skull Rapid. Near the head of the canyon are the remnants of the tiny town of Westwater, which has had an interesting and eventful history of its own, partly because of the river and canyon, partly because of the railroad that passes through it, and partly because of its remoteness. It has attracted over the years more than its fair share of colorful characters---government explorers and agents, boosters and get-rich-quick dreamers, cattle and sheep men, outlaws and bootleggers, and, of course, river runners. Mike Milligan, who came to know the area as a river guide, has written a thorough history of this out-of-the-way place. While it has a colorful history that makes its story interesting in and of itself, Westwater's significance derives more from a phenomenon of the modern West-thousands of recreational river runners. They have pushed a backwater place into the foreground of modern popular culture in the West. Westwater seems to represent one common sequence in western history: the late opening of unexplored territories; sporadic, often unsuccessful attempts to develop them; renewed obscurity when development doesn't succeed; their attraction of a marginal society of misfits or loners; and modern rediscovery due to new cultural motives, especially outdoors recreation, which has brought a great number of people into thousands of remote corners of the West.
