About this map

Skyline Dr traverses the high ridges of Sanpete County, providing access to a landscape defined by water management and high-altitude basins. Engineering and early irrigation history are visible through features like the Horseshoe Tunnel, Larson Tunnel, and Ephraim Tunnel, which pierce the mountain ridges to redirect flow. These subterranean works reflect a sophisticated effort to capture and distribute water across the varied terrain of Philadelphia Flat and Thistle Flat.

The area is punctuated by several small reservoirs and natural springs, including Petes Hole Reservoir, Loggers Fork Reservoir, and the remote Swens Spring. Many landforms carry the names of early settlers or cultural groups, such as Danish Knoll, Swedish Knoll, and Jolleys Hole, marking the ethnic heritage of those who worked these uplands. From the Lake Hill Campground to the high reaches of Haystack Mountain, the map documents a territory managed for both recreation and essential resource extraction.
