US 60 angles southeast toward Yeso, entering De Baca County en route. Curving back towards the east, the road enters Fort Sumner, the county seat, later. Just west of town, it serves as the northern terminus of NM-20, and in Fort Sumner proper, it begins a concurrency with US-84, which will persist for the remainder of the routes' miles in New Mexico. East of town the two highways encounter NM-212, a spur to Fort Sumner State Monument, and NM 252 in Taiban.
