South of Rangely and the White River, Unit 21 is east of the famous Book Cliffs in Utah and has good public access and abundant elk and mule deer. Some elk tags are sold over the counter, while all deer tags are limited. Hunters take many mature bucks.

Hunters and biologists have reported a dip in quality in recent years, but hunters who hunt hard usually find trophy class deer. Occasionally, a high quality buck is taken from the White River area in the north. Be aware of private land in the south. Lots of elk hunters who have bought over-the-counter tags have success since there is great access to most public land. Some outfitters also have prime private leases and private access to isolated BLM land.
