1973 Map of Rainbow Peak

About this map

Dewey Mine and the Sunnyside Mine define the high-altitude industrial activity of this mountain landscape within the Payette National Forest. This 1970s survey captures the remnants of a significant mining era, including the Twentieth Century Mill (Site) and scattered prospects along the steep drainages of Coon Creek and Cornish Creek. The terrain is marked by sharp peaks like Thunder Mtn and Lightning Peak, while the northern portion of the map includes Roosevelt Lake and a small Cem near Fall Creek, providing a point of interest for genealogists and local historians. The presence of numerous mining landmarks, including several U.S. Location Monuments like Uslm 4 and Uslm 5, indicates the heavy surveying required to manage claims across Gold Ridge and the Monumental Creek canyon.
