Peavine Peak, locally known as Peavine, is a smallish Basin-and-Range mountain about 7 miles northwest of downtown Reno, NV. It is clearly visible from most of the Truckee Meadows, the north-south-trending valley "where the Truckee runs through," the valley that contains the cities of Reno and Sparks. Unlike many basin-and-range mountains, Peavine's range-front fault is oriented in a northwest-southeast direction, and is down-to-the northeast. The steep, normal-faulted northeastern side of Peavine is seen on the left side of the photo below, which was taken from Highway 395 near Bordertown, looking more or less south. Also seen below, Peavine's southwestern side (seen to the right of the peak in this photo) is shallower, as though the original surface - prior to uplift and slight tilting to the southwest by faulting - consisted of low rolling hills.
The photo below shows Peavine as seen from the Truckee Meadows, from Highway 395 south of The Spaghetti Bowl looking to the north or northwest. In this photo, the steep northeastern side is to the right, and the shallower southwestern side is to the left. Mogul would be off the picture to the left.
Rocks on Peavine consist in part of the metavolcanic rocks of the Peavine sequence. These metavolcanic rocks are relatively old - Mesozoic, somewhere in the 70 to 250 million-year-old range. They consist of various kinds of volcanic rocks that have been metamorphosed, mostly to greenschist facies. As a report from the NBMG says, "These rocks tell of a time when this area was similar geologically to the Cascades of Oregon and Washington today, with frequent volcanic eruptions due to a subducting tectonic plate to the west." The volcanoes that created the Peavine sequence rocks are long, long gone. These old, metamorphosed volcanic rocks include metamorphosed felsic to intermediate flows and related plugs, metamorphosed felsic ash-flow and air-fall tuffs, and metamorphosed volcaniclastic conglomerates and sandstones.
Also, if you live in the Reno area, remember the local saying: don't plant until the snow is off Peavine. It isn't really spring until that happens.
