This file contains data for selected significant, buried Quaternary sediments, which is one layer of information on this CD-ROM, USGS Digital Data Series #38 (Soller and Packard, 1998). Together, all layers (10 of them) compose the digital version of a 1:1,000,000- scale map of Quaternary deposits (including both glacial and Holocene sediments) compiled for the glaciated area of the United States east of the Rocky Mountains (that is, the area covered by the Laurentide ice sheets). Parts of southern Ontario, areas beneath the Great Lakes, and parts of the submerged eastern seaboard are also included on the map. The paper version of the map is Soller (1993a, b, 1994, 1998, and in press). The map is a regional synthesis...

Cell maps for each oil and gas play were created by the USGS as a method for illustrating the degree of exploration, type of production, and distribution of production in a play or province. Each cell represents a quarter-mile square of the land surface, and the cells are coded to represent whether the wells included within the cell are predominantly oil-producing, gas-producing, both oil and gas-producing, or dry. The well information was initially retrieved from the Petroleum Information (PI) Well History Control System (WHCS), which is a proprietary, commercial database containing information for most oil and gas wells in the U.S. Cells were developed as a graphic solution to overcome the problem of displaying...
