Book is based on Blake's diaries as well as the diaries and field notes of other USGS party members, provides a detailed account of the US Geological Survey mapping expeditions of the San Juan Canyon in 1921, the upper Green River in 1922, and the Grand Canyon in 1923. Also tells the personal story of Blake, the young boatman who was the only man to be on all three trips. Based on Blake's diaries, as well as the diaries and field notes of other USGS party members, Rough-Water Man details the adventure, the hardships, mishaps, and personal conflicts that occurred on Blake's expeditions of the Colorado River. Traveling in small wooden boats, their passage was more difficult and more dangerous than it had been in previous expeditions because the men had to maintain a line of sight from one survey to the next. This forced them to land every few hundred yards, even in rapids or where the canyon walls were almost vertical. 259 pgs. Illustrated with BW photos and maps. Signed by Westwood on the pre-title page. A small old owners stamp inside the front cover. Otherwise a nice clean copy.
