2021 Map of Tin Cup Mountain

About this map

Beaver Divide and Beaver Rim form a prominent topographical spine across this Fremont County landscape, defining the high-altitude separation between drainage systems. The terrain is marked by sharp elevation changes, particularly around Tin Cup Mtn and the northern reaches of the Granite Mountains. In this arid environment, water management is evident through features such as the Daniel F Hudson Reservoir and Findlay Reservoir, which support local ranching and land use in an area otherwise reliant on scattered sources like Tin Cup Spring. The mapping details several deep drainages, including Logan Gulch and West Fork Horseshoe Draw, which channel seasonal runoff from the mountains into the creek systems below, illustrating the complex hydrology of the Wyoming high plains.
