Peavine Peak, the highest point on Peavine mountain, is located in Washoe County Nevada, at the northwest corner of the Truckee Meadows and about 3.5 miles (5.6 km) due east of the California state. It forms one of the most dominant geographical features in the Reno/Sparks area. Early prospectors to the mountain discovered wild pea vines growing in the vicinity of Peavine Springs on the northeast flank of the mountain, near Poeville, hence the name.
Much of the northern Truckee Meadows is built atop Peavine alluvium, most significantly from just west of Lake Park in Northwest Reno, across the campus of the University of Nevada-Reno, and toward Proctor Hug High School in Northeast Reno. Above these alluvial deposits, the sediments become coarser and are frequently interspersed with diatomaceous material.
Where the gentler lower slopes of the foothills join the significantly steeper slopes of the mountain proper, the sediments give way to their igneous parents. U.S. Highway 395 traverses the so-called Alta Formation, which is composed largely of pyroxene andesite flows, flow breccia, and laharic breccia. On the flanks of Peavine Mountain, the Alta Formation is frequently interrupted by rhyolite plugs and hornblende andesites of the Kate Peak Formation.
The higher reaches of the mountain display large outcroppings of granodiorite, many of which predominate the features on the upper reaches of the south slope. In addition, one of the most common features of Peavine's geology is the so-called Peavine Sequence, Mesozoic-aged altered and unaltered metavolcanic rock composed of a variety of material including rhyolite flows and pyroclastics, dacite, andesite, and laharic breccias.
