    Contact! by Callan Bentley from the GigaPan Contact between Tensleep Formation & Goose Egg Formation, east of Shell, Wyoming by Callan Bentley

    The Permian-Triassic Goose Egg Formation (orangey tan) overlies the Pennsylvanian Tensleep Formation (purple) in a roadcut west of Shell, Wyoming. The contact, originally horizontal, dips to the west, presumably due to Laramide deformation associated with the Bighorn uplift.
