1955 Map of Guide Rock

About this map

The Laramie Mountains dominate this high-altitude landscape in Albany County, where complex drainage systems like West Bluegrass Creek and East Bluegrass Creek converge. The topography is defined by significant vertical relief, from the namesake Guide Rock formation to the deep cut of Halleck Canyon. The map captures a specialized land use in the southern portion with the Sybille Game and Fish Experimental Unit, established along the banks of North Sybille Creek. This area's transition from the windswept height of Bluegrass Ridge down to the creek valleys is marked by isolated structures such as a lone School, reflecting the sparse, resource-focused settlement pattern of Wyoming's interior during the mid-20th century.
