Colorado Unit 40 Description
Unit 40 Located in Mesa County bounded on the North by the Colorado River; on the East by U.S. 50; on the South by Colorado 141 and Dolores River; on the West by the Utah border.
GMU 40 This 750 square mile unit consists of a relatively flat summit leading to sloping mesas bisected by deep, rugged canyons. The highest elevation range is approximately 9,800’. Roads provide access to the mesas, but many of the canyons are remote and accessible only by foot or horseback. Weather starts out mild but mud or snow accumulation is likely in later seasons. Early season hunters should favor higher elevations of the USFS land, while later season hunters will do better on the lower BLM lands. Hunters can find many water holes within the dark timber stands on north facing slopes. Elk and deer frequent these areas during warm temperatures and heavy hunting pressure. GMU 40 has a lot of private land, and public access to BLM is often difficult to reach by vehicle. There are some good bucks in GMU 40 but they are hard to locate. The upper end of the Little Dolores drainage is a good place for quality mule deer bucks but there is considerable private land. Late season hunters may have success near Seiber Canyon, but it is foot or horseback only. Areas along the Utah border and north of Gateway can be good during the rifle seasons however be aware of private land and the state line. Bulls will be bugling from mid-Sept through 1st rifle opening weekend. Elk are widely distributed. Most stay high until hunting pressure pushes them to lower elevations and less accessible drainage. Do not hunt areas that have previously received heavy hunting pressure – elk will not be there. Successful hunters do a lot of walking and looking.
