[2] The range lies to the south of the Long Valley Caldera.
The range is named after Jim Sherwin, a prospector who operated the first toll road across the Sierra.
It is well known for hiking opportunities in the summer, and backcountry skiing in the winter.
The range largely consists of reddish metamorphic rock, which are the roof pendant for the Sierra Nevada.
This rock was formed in the Paleozoic Era, and then was subsequently recrystallized and warped by the intrusion of the Sierra Nevada batholith underneath it.
