About this map

Grays Lake dominates this high-altitude wetlands landscape, serving as a central catchment for numerous seasonal drainages. The marshy basin is protected as the Grays Lake National Wildlife Refuge and Grays Lake NWR, providing critical habitat within the larger Caribou NF system. Topographic relief is provided by several distinct landforms that rise above the water level, including Bear Island and Bishop Island, along with the Little Gray Ridge to the southwest.

The presence of Clarks Cut and Outlet Valley indicates the managed nature of the hydrology here, where water is directed from the lake bed. Local road networks like W Side Rd and Grays Lake Rd skirt the edges of the marsh, connecting the small settlement of Gray to the surrounding ranching and forest lands. Significant tributaries such as Little Valley Cr, Willow Cr, and Eagle Cr feed into the basin, illustrating the complex drainage pattern across the Bonneville and Caribou County line.
