1968 Map of Fiftymile Flat

USGS Topo · Published 1991

About this map

Fiftymile Flat characterizes this high-plains landscape in Natrona County, where the intricate drainages of the South Fork Powder River meet an extensive network of ephemeral creeks and draws. Surveyed in the late 1960s, the map reveals a remote ranching environment defined by isolated landmarks like the Powder River Corrals and specialized sites such as Jack Ellis Camp. The presence of these named camps and corrals suggests the seasonal movement of livestock across this dry terrain, supported by man-made water sources like the Blue Hill Reservoir and Three T Reservoir.
