The Wyoming State Geological Survey is a state agency dedicated to studying, mapping, and sharing information about Wyoming’s geology, natural resources, and geologic hazards. Through research, publications, maps, data, and public outreach, the WSGS provides objective geoscience information that supports decision-making, education, resource management, public safety, and a deeper understanding of Wyoming’s geologic past, present, and future.

Toner, R.N.; Kehoe, K.S.; Colwell, D.J.; Wittke, S.J., 2024, "Geologic map of the Phantom Lake quadrangle, Carbon County, Wyoming", https://doi.org/10.15786/21758306, Wyoming Data Repository, V1
The Phantom Lake 7.5-minute quadrangle is in southeastern Carbon County near the western flank of Medicine Bow Mountains. Precambrian (Neoarchean–Paleoproterozoic) intrusive, metasedimentary, and metavolcanic units are exposed in the northern and south-central portions of the quadrangle, but are obscured by glacial tills and other Quaternary deposi...

Kehoe, K. S.; Hoppes, K. L.; Webber, P. M., 2020, "Preliminary geologic map of the Lion Bluffs quadrangle, Sweetwater County, Wyoming", https://doi.org/10.15786/20.500.11919/7103, Wyoming Data Repository, V1
The Lion Bluffs 7.5-minute quadrangle is located in southwestern Wyoming in the south-central part of the Rock Springs Uplift. The axis of the Rock Springs Uplift trends north–south through the western edge of the quadrangle, exposing Upper Cretaceous strata that dip shallowly away from the axis. These strata are largely covered by subhorizontal Ol...

Lichtner, D. T.; Toner, R. N.; Wrage, J. M.; Lynds, R. M., 2020, "Upper Cretaceous strata in the Powder River Basin—Formation tops database, structure and thickness contour maps, and associated well data", https://doi.org/10.15786/20.500.11919/7153, Wyoming Data Repository, V1
Upper Cretaceous strata in the Powder River Basin of northeastern Wyoming and southeastern Montana contain some of Wyoming’s most prolific oil and gas reservoirs as well as significant petroleum-generating source rocks. Using geophysical well logs from more than 2,200 oil and gas wells, key horizons within the Upper Cretaceous strata were identifie...
