Unit 110 sits in Bent and southern Otero County country—the lower Arkansas River corridor between Las Animas and the Kansas line, with the unit reaching south into Comanche Grassland country. Elevations 4,000 to 4,800 feet. The Arkansas itself is the unit's spine—a green ribbon of cottonwood, salt cedar, willow, and Russian olive cutting through irrigated farm ground (alfalfa, melons, onions in summer). North and south of the river the terrain is sandsage, shortgrass, and chico-rabbitbrush flats with shallow draws. The river bottom holds whitetail in pockets thick with brush; pronghorn cover the open uplands; mule deer work the breaks, the salt cedar tangles, and the cottonwood gallery. Public ground here is unusually generous for the southeast plains: John Martin Reservoir SWA is the big anchor (waterfowl-heavy but it produces deer along the riparian fringe), Adobe Creek Reservoir SWA, Setchfield SWA, Holbrook Reservoir SWA, plus Comanche National Grassland tracts on the southern side and a meaningful Walk-In Access roster (Bent County WIA listings tend to be useful for pronghorn and deer). US-50 runs east-west along the river; US-287 cuts north-south through Lamar and Springfield. Las Animas and La Junta are the working towns—gas, groceries, motels, processors. Cell service is reliable on US-50 and gets thin on the county grid. The whitetail rut in mid-November is the sleeper play—the Arkansas bottom can produce 150-class bucks and barely anyone targets them. The wind blows constant and the gumbo county roads turn to grease in any rain.
