1972 Map of Big Grassy Ridge

About this map

Big Grassy Ridge dominates this 1970s landscape in Fremont County, where volcanic activity and wind-blown deposits have shaped a distinct high-desert environment. The topography reveals a prominent Crater at the ridge summit and expansive fields of Sand Dunes that shift across the northern and southeastern sections of the quadrangle. Human activity in this arid region is tied closely to the few available water sources, notably Sandy Butte Well and Jenkins Well, which support livestock in an otherwise dry expanse. Transport relies on a network of rugged paths, including the primary Red Road and numerous unnamed Jeep Trails that snake through the North Junipers and South Junipers. This survey provides a clear view of the complex terrain at West Butte and within Hansen Basin, capturing the area as it functioned before modern shifts in land use or intensive development.
