Structural grids on the top Almond Formation (base Lewis Shale) and top Fox Hills Sandstone in the Eastern Part of the Southwestern Wyoming Province, Wyoming and Colorado
This child item contains one structural grid generated on the top of the Almond Formation (base Lewis Shale) and one grid on the top of the Fox Hills Sandstone. The top of the Lewis Shale and base of the Fox Hills Sandstone interfinger on a regional scale, so the top of the Fox Hills Sandstone was chosen as a structural horizon for consistency. The grids were generated by picking tops in borehole geophysical logs and interpolating between them in the Southwestern Wyoming Province in Wyoming and Colorado. The Lewis Shale in the eastern part of the province is bounded to the north and south by fault zones, to the east by uplift, and to the west by the Lewis stratigraphic pinch-out. The Lewis Shale has been uplifted and eroded throughout the Rock Springs Uplift and the grid, is therefore, null in this area. Overall, the Lewis Shale structural grids illustrate the complex tectonic architecture of the eastern part of the Southwestern Wyoming Province. Specifically, the grids highlight the Great Divide, Washakie, and Sand Wash Basins, and the associated Wamsutter and Cherokee arches. Depths to the grids are measured in feet relative to mean sea level. This is a child item of a larger data release titled "Digital Stratigraphic and Structural Grids of the Lewis Shale in the Eastern Part of the Southwestern Wyoming Province, Wyoming and Colorado".
