Simplified map of the Wyoming Province

Simplified map of the Wyoming Province—a craton composed of Archean-age continental crust. Archean- and Proterozoic-age rocks outcrop in many places within the Wyoming Province and are shown as dark grey blobs. The yellow blob highlights the location of the Hellroaring and Crevice plutons, a small portion of which are exposed in northern Yellowstone National Park. The boundary of Yellowstone National Park is outlined in yellow and labeled by the letters "YNP." Figure modified from Mogk et al., 2023, Geological Society of America Memoir vol 220.
