2021 Map of Iron Mountain

About this map

Iron Mtn and the surrounding high country of the Pine Ridge escarpment dominate this portion of northeastern Wyoming. The landscape is defined by its dramatic drainage patterns, where watercourses like Inyan Kara Cr and Arch Cr cut through the terrain, separated by prominent ridgelines such as the H K Divide and Nefsy Divide. This modern survey illustrates the enduring rural character of the region, showing how contemporary transportation routes like the Old Sundance Hwy and Sundance-Wind River Rd navigate the complex topography. The naming conventions, from Happy Cabin Rd to Tomcat Cr, reflect a heritage of ranching and localized landmark identification. The dense network of seasonal streams, including Mule Cr and Iron Run, emphasizes the hydrological importance of this area within the larger Powder River Basin watershed.
