2017 Map of Swan Lake

About this map

The Swan Lake settlement lies at the boundary of the Portneuf Range, marking a point of transition between the high peaks and the marshy lowlands of the south. This 2017 survey shows the intricate hydraulic network required to manage water in this high-altitude environment, featuring the Treasureton Canal and various named sources such as Dry Hollow Spring and Heart Mountain Spring. The southern portion of the quadrangle is defined by the significant wetland areas of Swan Lake Slough and Oxford Slough, which dominate the geography near Poverty Flats. Higher elevations are punctuated by family-named and topographic landmarks like Cedar Hill, Heart Mtn, and Dry Hollow Mtn. The road network, including Stockton Rd and Cottonwood Rd, follows the natural contours of the canyons and ridgelines, illustrating the persistent influence of the terrain on local movement and ranching access.
