Book Description
Glacial Lake Missoula and Its Humongous Floods tells the gripping tale of a huge Ice Age lake that drained suddenly--not just once but repeatedly--and reshaped the landscape of the Northwest. The narrative follows the path of the floodwaters as they raged from western Montana across the Idaho Panhandle, then scoured through eastern Washington and down the Columbia Gorge to the Pacific Ocean.

Book Description
Numerous environmental processes affect the development and stability of playa (lakebed) surfaces. Of special significance are hydrologic processes that control the amount and flow of both surface and ground water, and climatic variations which in turn influence the hydrology. This report, in six parts, examines some aspects of the playa surface environment. Chapter 1 is an introduction. Chapter 2 describes microrelief changes that developed at Harper Playa, California, following flooding of the playa in 1965-66. Chapter 3 documents a subsurface hydrologic investigation at Rogers Playa, California. The investigation revealed that the piezometric surface has lowered into sand layers beneath the surface, and it may explain why giant desiccation fissures have formed in the surface clays. Chapter 4 describes an investigation of seven Australian playas and suggests that Australia did not undergo a pluvial period like that of the western United States. Chapter 5 describes three kavirs (playas) in northern Iran and indicates that former lakes did exist there, but not to the same extent as in the western United States. Chapter 6 examines the possibilities of observing playa surface changes from satellites, using the present remote sensor technology. It also states that Gemini color photography and high resolution vidicon (TV) imagery are currently useful. (Author)
