1955 Map of Guide Rock

About this map

Guide Rock stands as a prominent landmark within this 1955 survey of the Laramie Mountains, where the landscape is defined by a dense network of high-altitude drainages and ridge systems. To the south, the Sybille Game and Fish Experimental Unit occupies a significant portion of the terrain, reflecting the mid-century focus on wildlife management and conservation in Albany County. The drainage patterns of Bluegrass Creek and its branches, including West Bluegrass Creek and East Bluegrass Creek, illustrate the complex topography of Bluegrass Ridge. This map captures the region during the Missouri River Basin development era, documenting the precise locations of remote canyons like Halleck Canyon and the headwaters of School Creek and Johnson Creek.
