Eastern Slope

From Carsonpedia

The Eastern Slope was a colloquial name for western Nevada in the 1850s, in the days before Nevada Territory was founded. The name referred to the eastern slope of the Sierra Nevada mountains, and included settlements such as Genoa, Washoe City, and the Eagle Valley. This area was also generally known as "Washoe". Officially these lands were part of Utah at the time, but being so far removed from Salt Lake City, and populated mostly by California transplants, they didn't identify much with Utah and were in search of their own identity. This later led to the creation of Nevada.
