About this map

Dunlap Sill rises as a prominent landmark along the border of De Baca and Chaves Counties, anchoring a high plains landscape defined by its intricate drainage systems. The terrain is carved by series of seasonal waterways including Wylie Draw, Huggins Draw, and East Fork Fivemile Draw, which eventually give way to the westward heights of Poquita Mesa. This modern survey reveals a ranching infrastructure heavily dependent on water management, evidenced by the numerous catchment points like Clardy Tank, Lake Tank, and Roosevelt Tanks scattered across the land.

Transportation through this high-desert region is concentrated along Fort Sumner Rd and N Main St, which cut a straight path across the township lines. Natural water sources are rare, making Gyp Spring and Horse Creek significant landmarks in an otherwise arid expanse. The map provides a contemporary look at the land division between t3s r22e and adjacent townships, illustrating the persistent grid of the Public Land Survey System in rural New Mexico.
