Unit 2A is the northwest corner pocket of GMU 2, defined as the chunk of the unit west of the Los Pinos River—the Pine Arm of Navajo Reservoir—and north of the San Juan River, tucked up against the Colorado line in San Juan County. Don't come in expecting mountains. This is high-desert mule deer country, mostly running 5,050 to about 7,200 feet, where you glass low sandstone hills, sage flats and cottonwood-choked river bottoms instead of dark timber. The deer are scattered and you earn every one, but the unit has a quiet reputation for kicking out a mature buck or two that drifted down off the better country to the north. Roughly two-thirds of it is public—a mix of BLM and state—so theres real ground to hunt, but it's broken up enough that an onX subscription is worth more than your binoculars some days. One thing to keep straight: 2A borders the Ute Mountain, Southern Ute and Navajo lands, but it is not on any of them. Your New Mexico tag is good here. Just dont let a wounded deer pull you across a reservation line, because that's a different jurisdiction and a different conversation. Access is the easy part and the trap at the same time. Good gravel and dirt roads thread most of 2A, but a lot of that network exists for oil and gas, so you'll share blind corners with pickup trucks doing 50—flag your vehicle and assume someone's coming. The dirt up here turns to gumbo the second a thunderstorm or an early-October skiff of snow hits, and two-track that was fine in the morning will strand a two-wheel-drive by dark. Cell service holds along US 64 and the bigger county roads out of Farmington, Aztec and Bloomfield, then dies as soon as you drop into the canyon breaks—download your maps before you leave pavement. Those three towns are your fuel, food and motel, with developed camping at Navajo Lake State Park on the east edge if you want to be closer. What sets 2A apart from its neighbors is honestly just how overlooked it is: it's flat, it's hot early, the deer density isn't going to wow anybody, and that's exactly why it stays uncrowded compared to the named units. Rattlesnake Canyon is closed to hunting, so check the proclamation boundary before you set up.
