2017 Map of Twentymile Butte

About this map

Echeta anchors the northwestern corner of this landscape, where the railroad meets the junction of Echeta Rd and the drainage of Wild Horse Cr. The terrain is defined by an intricate network of ephemeral watercourses and draws that carve through the high plains of Campbell County. Notable landmarks include the prominent Twentymile Butte and the steep contours of Snell Canyon. The map reveals a legacy of water management and cattle ranching through features like Twentymile Spring and numerous named draws such as Montgomery Draw, Felix Draw, and Barker Draw. These features suggest a working landscape where subtle topographic changes and seasonal water sources dictate movement and land use. The presence of Twentymile Cr and its tributaries like Rough Cr illustrates the complex drainage patterns that shape this portion of the Powder River Basin.
