The northwest corner of New Mexico, San Juan and Rio Arriba counties—Unit 2B is rolling sage-and-oak-brush hills with pinon-juniper patches stretching to the horizon in every direction. Navajo Lake, the state's second-largest, anchors the northern end and creates cottonwood-and-willow riparian corridors that draw game off the surrounding dry country like a cold beer draws hunters. Croplands near the water are where you want to be glassing at first and last light. Elevations sit between 5,500 and 7,500 feet, so nothing here will put you in an oxygen debt. Below the mesa rims its a patchwork of BLM, state trust, and Navajo Nation land—and the Navajo ground is closed to non-tribal hunting, so know your boundaries. Private ranches control big blocks around the irrigated valleys. NM 511, NM 539, and US 64 get you in on pavement, and most secondary roads are graded gravel that holds up fine in dry weather. Bloomfield is your supply town. Cell service is fair on the highways and garbage everywhere else. Weather is high-desert continental: hot days, cool nights in early fall, dust storms that come out of nowhere, and by late season the kind of snow that makes you question every decision you've made since drawing the tag. Navajo Lake — the state's second-largest lake — is in this unit. San Juan River in the northern portion. NM 511, NM 539, and US 64 provide access. Mix of BLM, state trust, and private. The lake draws recreationists so expect some non-hunting traffic during shoulder seasons. Aztec and Bloomfield to the north have services.
