Mud Flat Road runs immediately outside of the exclosure fence to the west. This small exclosure occurs in a saturated/subirrigated valley bottom associated with a headwater spring, and is bounded by low volcanic ridges. Most of the exclosure is dominated by Salix geyeriana/Carex utriculata community, with small Artemisia cana stands on the mesic fringe and Juniperus occidentalis on the bedrock.
