USGS Topo · Published 1957About this map
Ophir and its high-altitude mining district are the focal point of this mid-1950s survey of the San Juan Mountains. The landscape is defined by the complex transport networks required for mineral extraction, including the Rio Grande Southern RR and its distinctive Ophir Loop Sch, which navigated the extreme grades of the Howard Fork. Evidence of the region's hard-rock mining legacy is scattered across the peaks, from the Suffolk Mine near Silver Mountain to the Silver Bell Mine tucked beneath the Ophir Needles.
