1964 Map of Bridgeport

About this map

Gold mining legacies and remote settlements define this high-desert landscape on the border of Baker and Malheur counties. Along the Burnt River and Clarks Creek, extensive Dredge Tailings mark the industrial history of Bridgeport and China Town. The map reveals a dense concentration of mining operations near Pedro Mountain and California Mountain, including the Humboldt Mine, Summit Mine, and the Monohon Tunnel. These operations were supported by a network of vanished camps and towns like Clarksville and Malheur City, the latter of which features a local Cem. In the southern reaches, the Malheur Reservoir sits below Reservoir Butte, while the broad expanse of Cow Valley provides a stark contrast to the mine-pockmarked peaks to the north. Numerous springs, such as Rooster Comb Spring and Thompson Spring, are critical landmarks in this arid terrain, connected by a network of primitive roads and jeep trails.
