The Elko area, in northeastern Navada, lies in a northeast-trending structural valley that is filled with Quaternary deposits and Tertiary sedimentary rocks to a maximum depth of about 4,500 feet. The deepest part of the valley is centered west of Elko. The valley-fill deposits in the remainder of the valley have an average depth of about 2,500 feet. The depth estimates were made from about 200 g
