CO Mule Deer Unit 121

CO 121 — Tactical Analysis. Terrain & Access CO 121 spans 671,000 acres across the Colorado plains and breaks country at 4,150–5,100 feet elevation. Public land availability is severely limited at roughly 5%, making this a predominantly private-land unit. Hunters will need landowner access or outfitter relationships to reach huntable ground. Terrain transitions from rolling prairie to pinyon-juniper breaks; the limited elevation range means little vertical variation for tactical repositioning during hunts. Herd Quality Recent survey data shows a buck:doe ratio of 68:100 — an exceptionally high ratio that almost certainly reflects a small survey sample size..
