1973 Map of Bismark Mtn

About this map

Payette National Forest dominates this high-altitude landscape along the border of Idaho and Valley counties. The 1970s terrain is defined by a series of steep drainages and prominent divides, notably Eighty-eight Ridge and Ramey Ridge, where surveying crews established markers like Uslm 3212. The presence of Copper Camp and the Monumental Bridge crossing over Monumental Creek suggests the area's legacy of backcountry activity, likely tied to prospecting and forest management. Small-scale mining and exploration are evidenced by Prospect Creek and the named landing at Monumental Bar. Transportation across this challenging environment relied heavily on established trails, including the Pack Tr and various Jeep Trails that connected isolated points like Ramey to the broader river system of Big Creek.
