The Fairview Peak fault zone is the most readily accessible area of 14 examples of historical surface faulting in the Basin and Range Province. It also provides a classic example of the kinds of seismo tectonic events that, with many repetitions in the last 10 or 20 million years, have developed the geologic features of this province (Slemmons, David B., and John W. Bell, 1987).

One of the things that surprised me was that the central Nevada
mountain ranges are bare above the Pinyon-Juniper belt. Not until
we got to eastern Nevada did a Ponderosa Pine or Rocky Mountain
White Fir zone appear above the Pinyons and Junipers. Why might this
be?

| Keystone Junction
The first mine discovered in the Robinson Mining District, was the Elijah, near Lane City. The famed open-pit copper mines of Eastern Nevada including the Liberty Pit, largest in the state, are located in this mining district. Through the first half of the 20th century, this area produced nearly a billion dollars in copper, gold and silver. The huge mounds visible from here are waste rock which was removed to uncover the ore. Lane City, originally called Mineral City, was settled in 1869 and had a population of 400. At Mineral City was the Ragsdale Station--a hotel and a stage station. There is a collection of Frasera albomarginata from Keystone.
