The Mojave River is the largest of the streams and rivers that flow through southwestern San Bernardino County, CA. It extends more than 100 miles east from its source in the San Bernardino Mountains to the end east of Afton Canyon. This 3D animation takes the viewer on a tour of the entire length of the river.

The Clear Lake Hitch was formerly highly abundant and a staple food for the Pomo tribes of the Clear Lake region. The original abundance of this fish species is unknown but is believed to have declined 100-fold.
