1963 Map of Y B O Canyon

About this map

Goshen Hole Rim defines the dramatic geological shift in this portion of Goshen County, where the high plains break away into a complex system of drainage and erosional features. The terrain is dominated by a series of deep cuts including YBO Canyon, Sawmill Canyon, and Little Josh Canyon, which funnel water toward the lower elevations. Scattered throughout this arid landscape are vital water sources labeled simply as Springs, supporting the livestock operations that anchor the area's economy. Highlighting the settlement patterns of the mid-20th century, the map identifies established grazing hubs such as Werner Ranch in the north and Smith Ranch further south. Below the rim, the expanse of the Iowa Center Flats illustrates the transition from the rugged canyonlands to the more level grazing and agricultural lands that characterize the interior of the Goshen Hole.
