After more than 50 years of plans to dam the Green River, it finally happened in 1963 as part of the Colorado River Storage Project. Today many people enjoy boating and fishing on the resultant Flaming Gorge reservoir, but few know about what lies under the water. Unlike Glen Canyon, Flaming Gorge has received little attention. In Lost Canyons of the Green River, Roy Webb takes the reader back in time to discover what lay along this section of the Green River before the Flaming Gorge Dam was built, and provides a historical account of this rather neglected section of the Colorado River system. A historian and a lifetime lover of rivers, Webb has spent decades exploring the region, digging into archives, and running the length of the Green River. The book chronicles the history that is most closely linked to the river and its bottomlands, sharing the stories of those who travelled the Green through Flaming Gorge and the other canyons now flooded by the reservoir, as well as those who lived, farmed, trapped, or ranched along its banks. In depicting the river of the past, Webb considers his book a guidebook for a river you can no longer run.
