Backed by the striking silhouette of Lone Cone mountain, Groundhog is the largest body of water in Dolores County and a remote destination that is mostly accessible from May through September. Although the reservoir frequently seems empty of birds, a spotting scope will usually reveal good numbers of ducks and Western and Eared Grebes; sometimes shorebirds, Bald Eagles or Ospreys, and even Surf Scoters have been seen. This is also one of the best places in Colorado to find Purple Martins, which nest in the aspen groves near the water and sometimes forage over the parking lot. The wet meadow and aspen habitats surrounding the reservoir can serve up breeding birds like Lincoln’s and Fox Sparrows. Elk are common in the area, as are deer, coyotes, foxes, and the marmots for which the reservoir is named.County: Dolores
