About this map

The North Platte River winds through this portion of Wyoming, anchored by the massive Glendo Dam and the northern reaches of Glendo State Park. The landscape is a complex network of hydrologic features and rugged elevation changes, where the Glendo Reservoir meets dramatic landforms like Bulls Bend and Stroda Point. For historians, the map's most compelling detail is the path of the Emigrant Trail, which cuts across the western half of the quadrangle, paralleling the river's ancient corridor.

Local development is concentrated around the small settlement of Cassa and vital infrastructure including the Spillway and various Gaging Stations. Water management is evident through numerous smaller catchments like Hooley Reservoir and Twiford Res, which support the drainage basins of Horseshoe Creek and the various forks of Bear Creek. The terrain is marked by significant canyons, notably Sawmill Canyon and Wendover Canyon, providing a clear look at the topography before modern development altered these drainage patterns.
