Self, Robert T. Ryder, Ronald C. Johnson, Michael E. Brownfield, and Tracy J. Mercier Introduction Stratigraphy of the Green River Formation, Wyoming For several decades, the U.S. Geological Survey (USGS) has collected cores, drill cuttings, and other subsurface data from boreholes drilled to evaluate the oil shale deposits in the The Green River Formation consists of lacustrine and Eocene Green River Formation, as well as from oil and gas fluvial-lacustrine rocks that were deposited in and adjacent to tests, in the Greater Green River Basin of southwestern Wyo- the Eocene Lake Gosiute that covered much of southwestern ming, northwestern Colorado, and northeastern Utah (fig. 1). Wyoming, northwestern Colorado, and northeastern Utah The Greater Green River Basin (GGRB) is the name given to from roughly 52.5 to 47.5 Ma (Smith and others, 2008). The a group of five sub-basins. The names of these sub-basins and lake formed in a structural and sedimentary basin that formed their locations within the Greater Green River Basin are as during the Laramide orogeny, a major mountain-building epi- follows: (1) the
