Preliminary map showing the thickness of glacial deposits in Ohio

This map was compiled as part of a U.S. Geological Survey project to portray the character and thickness of glacial deposits east of the Rocky Mountains. It is a preliminary map, compiled at a scale of 1:250,000 from sources of differing type and quality (fig. I, table 1). County drift-thickness maps produced by the Ohio Geological Survey are the most reliable source of data used. These county map

Reconnaissance surficial geologic map of northern Death Valley, California and Nevada

Sedimentary deposits of northern Death Valley include units of alluvial, eolian, lacustrine, and spring origin.  The alluvial deposits, which include both fan and pediment deposits, predominate.  Fan deposits are divided into four major units; locally one of these is further divided into three subunits.  Pediment deposits may be divided into two subunits.  Hyphenated map symbols (for example, Qf4-
