1963 Map of Y B O Canyon

About this map

The Goshen Hole Rim forms a dramatic topographical boundary across this portion of southeastern Wyoming, separating the elevated Iowa Center Flats from the complex drainage systems below. This 1963 field-checked survey highlights a series of deeply incised canyons that cut through the rim, including Barns Canyon, Sawmill Canyon, and the central YBO Canyon. These geographic features dictate the placement of ranching operations and water sources in an otherwise arid landscape. Scattered ranch sites such as Werner Ranch near Elder Creek and the Bogville Ranch on Corn Creek illustrate the historical reliance on these scarce waterways. The map also traces a network of unimproved dirt roads and light-duty paths that navigate the breaks in the rim, connecting isolated livestock operations to the broader Goshen County region.
