2013 Map of Milner Butte

About this map

Milner Butte rises as a prominent landmark above the surrounding high desert terrain on this modern survey of the border between Twin Falls and Cassia counties. The landscape is defined by the critical irrigation infrastructure of the Snake River Plain, most notably the Twin Falls Main Canal and Milner Main Canal, which redirected water to transform this arid region into productive agricultural land. These man-made waterways contrast with the natural drainage patterns of Big Cottonwood Cr and the reservoir at Murtaugh Lake. In the southern portion of the map, the terrain becomes more varied as Mountain Meadow Cr descends from the foothills. The gridded network of rural roads, such as Us-30 E and various township lines, illustrates the systematic development of Idaho's agricultural interior a century after the first large-scale irrigation projects began.
