USGS Nixon, Wadsworth and Spanish Springs Valley 15 minute quads
The Pah Rah Range is a mountain range located in western Nevada in Washoe County just to the northeast of Reno. It is a hook shaped range with the main eastern portion oriented northwest–southeast, approximately 20 miles (32 km) long. The northwest flowing Cottonwood Creek in Warm Springs Valley is bounded on three sides by the range. To the south and east the Truckee River forms the boundary and Pyramid Lake is at the northeast. Spanish Springs Valley north of Reno forms the southwest margin. To the north, the narrow Mullen Pass separates the Pah Rah Range from the Virginia Mountains.
The highest peaks (in order from south to north) are Pond Peak (elevation 8,035 ft (2,449 m)),[2]Virginia Peak (elevation 8,357 ft (2,547 m)) and Pah Rah Peak (elevation 8,249 ft (2,514 m)).[3] In the southwest portion Spanish Springs Peak (elevation 7,404 ft (2,257 m)) is the highest.[4] Both Pond Peak and Virginia Peak host several radio towers. Virginia Peak is also the site of a doppler radar station.
"Pah Rah" is a Paiute term which translates roughly to "Lake Mountain" in reference to Pyramid Lake adjacent to the northeast margin of the range. This term applies to the Virginia Mountains better. This apparent mix-up is likely due to confusion on the part of the early surveyors of the region.[citation needed]
Olinghouse mining district
The former community[6] and historic mining district[7] of Olinghouse is located in the southeastern foothills of the Pah Rah Range about 8 miles (13 km) WNW of Wadsworth, Nevada and 2 miles (3.2 km) east of Pond Peak.[8] The mines of the district produced gold from placer deposits and veins associated with graniteporphyrydikes in a faulted basaltic to andesitic volcanic terrain of Oligocene to Miocene age.[9] Mining for gold as collector's specimens occurred during the late 1990s and early 2000s.[9]
The area had four names: White Horse, McLanesville, Ora and finally Olinghouse.[10] The district and the former town that served it were named for Elias Olinghouse, who settled there and ran a mule team transport service.[11][12]
The Olinghouse post office was in operation from October 1903 until July 1923.[13]
