2020 Map of Cactus Flat

About this map

The Marias River carves a winding course through this section of the northern plains, marking the boundary between Toole Co and Pondera Co. The landscape is defined by the broad plateau of Cactus Flat and the deep drainage of Millar Coulee, illustrating the erosional patterns of the High Plains. Evidence of local land management and water infrastructure is visible through features like the An Canal and Heron Lake in the southern portion of the quadrangle. The road network, including Bullhead Rd and Hjartarson Rd, follows the rectangular section lines of the Public Land Survey System, a testament to the systematic agricultural development of Montana's rural interior.
