Blythe, California, is an isolated city in the northern end of the Palo Verde Valley of the Colorado River on the Arizona border. It is at the junction of Interstate 10 and U.S. highway 95.

Located in the Lower Colorado Valley of the Sonoran Desert, the region consists of sandy or gravely plains, low mountains, sand dunes and alkali sinks. Drainage channels, known as washes, store water to support trees and large shrubs along their banks.

The Palo Verde Tree
The palo verde, "green branch" in Spanish, is common in the region.

Agriculturally based and heavily impacted by two state prisons and tourism, Blythe has a population of 21,500, and the general area about 30,300. The population more than triples during the winter months, with the arrival of Snowbirds, visitors seeking relief from cold climate in other parts of the country and Canada.

The Colorado River Recreation Area extends from Yuma, Arizona, to Lake Powell, a distance of about 650 miles. The area offers boating, fishing, hunting and other water sports. There are almost 95 miles of navigable water between Blythe and Imperial Dam in Yuma

Earthquakes

Although California is remembered for its earthquakes, Blythe is one of the most seismically stable cities in the Western States. There has not been an earthquake centered here in over half a million years. Earthquakes centered as far away as the Los Angeles area are felt here, however, and the alluvial nature of the Palo Verde Valley soil intensifies the effect.
