It seems unbelievable, but a small corner of Nevada actually lies in the California region. That corner is the westernmost part of Nevada, which includes Reno, Carson City, and Lake Tahoe.
Although all of Nevada has earthquakes, this part is most seismically active. Other than that, the Reno-Carson City-Lake Tahoe area doesn’t have a lot in common with California. It doesn’t suffer from a shortage of water, doesn’t have smog, and is not subject to the perils of urban congestion. It also doesn’t have a huge agricultural industry. It’s hard to figure out why it’s considered part of the California region.
