Book Description
The Late Cenozoic history of the western Grand Canyon is one of profound and rapid transformation. The constantly changing morphology and dynamics of the canyon during this period have been recorded in spectacular geologic features, such as frozen lava cascades and lava dams, as well as volcanic cones, necks, and dikes. All of these unique features, which make the western part of the Grand Canyon strikingly different from other parts, resulted from the interaction of basaltic lava flows and vigorous erosion by the Colorado River. The volcanic phenomena in the Grand Canyon were created by eruptions of basaltic lava in the southernmost part of the Uinkaret volcanic field. Some lava flows were extruded on the Uinkaret Plateau and cascaded over the outer rim of the Grand Canyon into Toroweap Valley and Whitmore Wash, while others were extruded within the Grand Canyon itself and partly covered the Esplanade Platform. The remaining flows cascaded over the rim of the canyon's inner gorge. Red molten rock cascading into the canyon and forming lava dams must have presented a spectacular scene, the likes of which have never been viewed by human beings. Even more spectacular is how quickly these lava dams formed - from small single-flow dams that were created in only a few days, to complex, multiple-flow dams that took several thousand years. The dams were then destroyed when the water impounded behind them ultimately overflowed. Although their construction and destruction occurred in a geologic instant, these events were the most significant in the late Cenozoic history of the Grand Canyon. Because of the largely inaccessible nature of the western part of the canyon, the author and his field assistants researching this area had to be creative in their data-gathering techniques. For example, they made photo mosaics of the entire canyon wall using a hand-held aerial camera; these mosaics served as cross sections on which all geological data were plotted. In addition, to photograph features hidden from view at river level, they utilized light aircraft and helicopters. Finally, a professional mountain climber collected samples from various units exposed high on vertical cliffs. Memoir 183 is a compilation of this field work, which took more than two decades to complete. It contains numerous maps, photographs, and cross sections of frozen lava cascades and the remnants of a sequence of 13 major lava dams that once formed huge barriers to the Colorado River. The volume also discusses the history of lakes that formed behind these lava dams and the associated sedimentary deposits that once partly filled the Grand Canyon. The results of this study provide new insights into the rates at which the Colorado River is able to downcut its channel, as well as the major factors that controlled erosion of the Grand Canyon.

Book Description
From one of Outside magazine’s “Literary All-Stars” comes the thrilling true tale of the fastest boat ride ever through the Grand Canyon, atop the legendary Colorado River flood of 1983. In the spring of 1983, massive flooding along the length of the Colorado River confronted a team of engineers at the Glen Canyon Dam with an unprecedented emergency that may have resulted in the most catastrophic dam failure in history. In the midst of this crisis, the decision to launch a small wooden dory named “The Emerald Mile” at the head of the Grand Canyon, just fifteen miles downstream from the Glen Canyon Dam, seemed not just odd, but downright suicidal. The Emerald Mile, at one time slated to be destroyed, was rescued and brought back to life by Kenton Grua, the man at the oars, who intended to use this flood as a kind of hydraulic sling-shot. The goal was to nail the all-time record for the fastest boat ever propelled—by oar, by motor, or by the grace of God himself—through the heart of the Grand Canyon atop the Colorado River from Lee’s Ferry to Lake Mead. Did he survive? Just barely. Now, this remarkable, epic feat unfolds here, in The Emerald Mile.

Book Description
This second edition of the leading book on Grand Canyon geology contains the most recent discoveries and interpretations of the origin and history of the canyon. It includes two entirely new chapters: one on debris flow in the Canyon and one on Holocene deposits in the canyon. All chapters have been updated where necessary and all photographs have been replaced or re-screened for better resolution. Written by acknowledged experts in stratigraphy, paleontology, structural geology, geomorphology, volcanism, and seismology, this book offers a wealth of information for students, geologists, and general readers interested in acquiring an understanding of the geological history of this great natural wonder.
