1960 Map of Black Mountain

About this map

Big Horn National Forest dominates this mountain landscape, defined by the dramatic descent of Shell Creek through the steep-walled Shell Canyon. The 1960 field survey captures an era of scientific and recreational activity in the wilderness, evidenced by the Iowa State Univ Geology Camp and the nearby Post Creek Picnic Area. Water management for lower-lying basins is clearly visible through a network of high-altitude irrigation features, including the Kershner Ditch, High Line Ditch, and Hatten Ditch, which trace the contours above Trapper Creek. To the south, the Trapper Lodge Ranch sits near the confluence of mountain streams, while distinctive landmarks like Elephant Head Rock and Chimney Rock serve as natural navigational aids. The presence of a Gaging Sta on Shell Creek underscores the importance of monitoring snowmelt and runoff in this critical watershed.
