Product Description
by William a. Szary (Author)
Glacial Lake Bonneville preceded glacial Lake Missoula in forming catastrophic flooding through Idaho and Washington. Much of the field evidence of the Bonneville floods were destroyed in Washington state by the younger Lake Missoula floods in the side canyons south of the Lower Granite Dam to Clarkston, Washington, and in the side canyons along the Hells Canyon along the Idaho-Oregon border.The book, Glacial Lake Bonneville, traces the lake history in Utah, the dam breakage in Idaho, and the resultant flood pathway through the Snake River Plain of southern Idaho, Hells Canyon along the Oregon state line, into Washington, ending in the Tucannon Valley. Chapter 1 begins the story in Utah with field evidence of Lake Bonneville, Utah Valley's stratigraphy, and glacial deposits. Chapter 2 presents the field evidence of Lake Bonneville in Utah with identification of specific sites used to characterize the lake. Chapter 3 begins tracing the lake and flooding in Idaho. Chapter 4 presents evidence in Eastern Idaho along with field evidence. Chapter 5 ends the tale with field evidence in Washington State, presenting sites where sedimentary deposits can be viewed, most of which are from Lake Missoula flooding.
