1966 Map of Thornburgh

About this map

Thornburgh (Historical Site) marks a point of significant local heritage within this 1960s survey of the high country straddling the Rio Blanco and Moffat county line. The landscape is defined by the intersection of resource extraction and mountain wilderness, featuring the Thornburgh Gas Field to the northeast and the northern reaches of the White River National Forest to the south. The terrain rises sharply toward Thornburgh Mountain and Uranium Peak, while hydrological engineering is evident through the Wilson Ditch and Ferguson Ditch No 2. This era of land use is further documented by the presence of numerous prospects and drill holes, highlighting the mineral and gas exploration that shaped the local economy. Water features like Aldrich Lakes and Wyman Reservoir suggest a reliance on managed water sources in this high-elevation environment.
