How BLM hunting works in Colorado
BLM: "Unless specifically prohibited, public lands managed by the BLM are open to hunting." Colorado licenses and seasons apply. Many BLM parcels are surrounded by private land; crossing private land to reach them needs the landowner's permission. Field office pages do not list species, so the GMU seasons decide what is open. Acres below are each field office's own statement where it gives one; Grand Junction, Kremmling and White River give no number, so their acres are GIS acres of BLM land inside the office boundary.
