About this map

De Lamar and the neighboring settlements of Dewey and Democrat define the industrial and residential footprint of this Owyhee County mining district. The landscape is dominated by heavy extractive activity, centered around the massive DeLamar Mountain and Florida Mountain. This survey illustrates the modern scale of mining operations, featuring extensive pits like Glen Silver Pit Number 1 and Sommercamp Pit, alongside historical sites such as the Garfield Mine and Wagontown.

Water management for these operations is evident through the Delamar Tailings Dam and the network of drainages including Jordan Creek and Pole Creek. The terrain is marked by numerous gulches that historically served as focal points for prospecting, from Slaughterhouse Gulch to Negro Gulch. This record captures the transition between early 20th-century lode mining and the expansive open-pit methods of the late 20th and early 21st centuries.
