1955 Map of Rattlesnake Pass

About this map

The Overland Trail cuts across the high Wyoming landscape in this mid-century survey, tracing a historic path through Rattlesnake Pass. The area is defined by the massive rise of Elk Mountain and the prominent Halleck Ridge, where high-altitude drainage systems like Rattlesnake Creek and Halleck Creek carve through the terrain. Evidence of the region’s ranching history and early infrastructure is visible at Mullen Ranch and Palm Ranch, while the Fort Halleck Memorial marks a site of military and pioneer significance.
