Rare in this arid corner of Southwest Colorado: County Line Ranch carries five ponds, three of them holding water year-round, on 535 acres in the heart of GMU 711, a unit known for trophy mule deer. The ranch qualifies for the Colorado Landowner Preference Program and offers over-the-counter elk tags, giving owners consistent hunting access without waiting on a draw. The ranch also sits in an area with a substantial resident elk herd, and as rifle seasons roll around and weather pushes in on the high country, additional herds migrate down through the property, stacking on top of the resident population for some of the most consistent elk activity in the region. That water is what sets the wildlife habitat apart. Combined with native grass meadows, timber pockets, gamble oak, and rolling topography, it draws and holds mule deer and elk while also supporting solid grazing capacity. Roughly 320 acres of BLM land border the east side, and the ranch sits just 2 miles from tens of thousands of additional acres of BLM and national forest, extending the recreational footprint well beyond the fence line. An established network of two-track roads reaches every corner of the property for hunting, livestock work, or simply exploring. Access is year-round via a maintained county road to a gated entrance, and the ranch is fully fenced and cross-fenced, ready to run livestock from day one. Power runs along the county road, and a Montezuma Rural Water Company tap is available at the road (buyer to verify), leaving the door open for a cabin, barn, or full build-out down the line. County Line Ranch is being offered as part of a larger ranch under division, with final acreage confirmed by survey. Properties combining reliable year-round water, trophy mule deer genetics, resident and migratory elk, and direct access to public land rarely come to market this is a true legacy ranch opportunity for a buyer looking to build something that lasts for generations in Dolores County.
