1971 Map of Patterson Crossing

About this map

Purgatoire River carves through this arid landscape in Las Animas County, where early water management is evident through systems like the Lewelling Mc Cormick Ditch and the Patterson Ditch. The terrain is defined by deep incisions such as Purgatoire Canyon, which dictates the movement of cattle and commerce across the high plains. The namesake Patterson Crossing serves as a critical point of navigation over the river, supplemented by technical markers like a Gaging Sta and a remote Cable Crossing.
