The Purgatoire River valley and its intricate irrigation systems dominate this southern Colorado landscape near the settlement of Hoehne. Tracing the local water management reveals a complex network of channels, including the Hoehne Ditch, Chicosa Ditch, and Picketwire Ditch, which support the agricultural life of the region. To the north, the Black Hills rise above the drainage of the Black Hills Arroyo, while the Model Reservoir and Model Dam stand as significant landmarks of water storage in this arid environment.
