Colorado Unit 421 Description
Unit 421 Located in Mesa and Garfield Counties bounded on the North by the Colorado River-Plateau Creek divide; on the East by Divide Creek-Buzzard Creek divide; on the South by Mesa-Delta Co. line; on the West by Colorado 65.
GMU 421 Grand Mesa terrain ranges from high elevation (11,000’) spruce/fir forests to low elevation (4,800’) pinyon-juniper woodlands. Weather can be rainy or snowy, then warm up and dry out the following day. Roads can become very muddy and 4WD is recommended. Hunters should be prepared to spend time on foot or horseback. Much of the area is public land. Overall, the hunting pressure is heavy. Deer are found on forest lands and higher elevation private lands during Oct. The resident deer stay in lower agricultural areas year round. The migrating deer herd begins to move off the forest to lower elevations in mid-Nov, often to BLM lands. The best deer hunting is at mid elevations (8,500-9,500’), with more buck opportunities in the later seasons. The Battlements can be good in late seasons, but the terrain is rugged. The open country offers good opportunities for those who get out on foot or horseback. The elk herd is well distributed with good hunting success expected. Elk are scattered throughout the forest and on private lands. Most elk stay at higher elevations (8500- 10,000’) in thick timber and oakbrush. There is no migration during the season, movement to the more remote areas is in response to hunting pressure. They will seek classic cover – the heavily wooded, north-facing slopes near water. You will need to get away from the roads. There are lots of legal bulls as the area is managed for quantity of bulls rather than trophy status. Hence, trophy bulls are present but relatively rare.
