Water and the arid zone of the United States

In a pluvial period associated with Wisconsin glaciation the closed basin of the Estancia Valley in New Mexico held a lake which, at its maximum extent, was 150 feet deep and had a surface area of 450 square miles. This basin, with a mean elevation of about 6,000 feet, has at present an annual precipitation of about 14 inches.Estimates have been made of the Pleistocene precipitation necessary to m

Geology of Seattle, a field trip

Older Quaternary deposits are locally exposed.Most of the city is underlain by up to 100 m of glacial
