1966 Map of Danish Knoll

About this map

The Manti-La Sal National Forest in Sanpete County is defined here by its complex water management infrastructure and high-elevation research facilities. In the mid-1960s, the landscape featured a sophisticated network of canals and underground works, including the Ephraim Tunnel, Larsen Tunnel, and Horseshoe Tunnel, designed to move water across the rugged Wasatch Plateau. These engineering feats are complemented by agricultural research sites like the Great Basin Experiment Station and the Alpine Experiment Station, which underscore the region's importance for land management studies. Higher elevations along Skyline Drive reveal a series of distinctively named peaks and basins, such as Danish Knoll, Swedish Knoll, and the Soup Bowl. Recreational sites like Lake Hill Campground and high-country reservoirs including John August Lake provide a clear view of the area's mid-century utility as both a resource hub and a public refuge.
