About this map

Plumasano Basin sits at the heart of this high-altitude landscape along the border of McKinley and Cibola Counties. The topography is defined by significant landforms like the broad Pie Mesa and the nearby Red Mesa, which separate various drainage systems. Water movement through this arid environment is traced by the seasonal courses of Plumasano Wash and Willow Wash, alongside deep cuts such as Yellowrock Canyon and Mullen Canyon.

Access across these mesas is provided by a network of service roads, including Indian Svc Rte 33 and Indian Svc Rte 8. This modern survey illustrates how traditional land boundaries, such as those for Townships 8 and 9 North, continue to organize this New Mexico terrain. The map captures a moment in the 21st century where historical land management routes like Pia Mesa Rd remain essential for navigating the complex geography of Thompson Draw and its surrounding plateaus.
