1955 Map of Guide Rock

About this map

The Laramie Mountains dominate this mid-century survey, showcasing a complex network of drainage systems such as Bluegrass Creek and Halleck Creek that carve through the high terrain. The map captures the establishment of the Sybille Game and Fish Experimental Unit in the southeast, reflecting Wyoming's early scientific approaches to wildlife management and conservation. Notable geological and navigational landmarks like Guide Rock and Bluegrass Ridge provide vertical orientation for the area's watershed. The presence of numerous named canyons and draws, including Halleck Canyon and Tower Canyon, suggests a landscape shaped by seasonal water flow and cattle grazing routes. Historical researchers will find value in the specific naming of small tributaries like School Creek and Johnson Creek, which often trace their origins to early ranching families or rural schoolhouse locations that once served this high-country community.
