This is a coverage of the Colorado Plateau coal assessment study area. The study area outline was drawn on the county lines that most closely outline the coal-bearing rocks in the Colorado Plateau Region. The county outlines originate from a national coverage for which lines were extracted from U.S. Census 1990 TIGER/line files using an AML program written by Nebert, D., and Negri, M., USGS-Water Resources Division (WRD), running on two Data General 6220 servers.

Aeromagnetic data were collected along flight lines by instruments in an aircraft that recorded magnetic-field values and locations. This dataset presents latitude, longitude, altitude, and magnetic-field values.
Crushed stone and sand and gravel are the main types of naturalaggregate used in the United States. Aggregate is used in nearlyall residential, commercial, and industrial building construction,and in most public works projects including roads and highways,bridges, railroad and light rail beds, airports, water and sewersystems, and tunnels. Much of the infrastructure built during the1950s and 1960s has deteriorated to a point that requires extensiverepair or replacement. All this construction requires enormousamounts of aggregate. In Colorado, for example, nearly 45 milliontons of aggregate, or about 12 tons per person, were producedduring 1994.
