By David A. John and Chester T. Wrucke


thumbnail view of the map

The Izzenhood Spring quadrangle covers about 145 km2 of the southwestern part of the Sheep Creek Range in northern Lander County, Nevada. The quadrangle is underlain by Lower Paleozoic rocks that are unconformably overlain and intruded by thick sequences of Miocene igneous rocks related to the northern Nevada rift (Stewart and McKee, 1977; Wallace and John, 1998; John and others, 2000). Much of the eastern part of the quadrangle is covered by thin Quaternary surficial deposits.
