2017 Map of Boundary Ridge

About this map

Boundary Ridge serves as a critical geographic marker where the borders of Idaho, Wyoming, and Utah converge. This high-altitude terrain is defined by a series of deep drainage basins and canyons, including Red Rock Canyon and North Lake Canyon, which channel water into creeks like Pegram Creek and Christy Creek. The presence of Shearing Corral Hollow and Windmill Draw suggests a landscape historically utilized for livestock and ranching, supported by infrastructure like the Poison Creek Reservoir. Small settlements and ranching outposts like Taylor are connected by a sparse network of roads, including Humburg Ranch Rd and Dry Hollow Rd. The map illustrates the complex intersection of county and state lines, notably the divide between Bear Lake and Lincoln counties, as the land rises toward Red Mountain.
