The Amargosa River is a unique desert waterway flowing approximately 185 miles through southern Nevada and eastern California before eventually disappearing into the ground in Death Valley. Often called the "Crown Jewel of the Mojave Desert," it's the only free-flowing river in the Death Valley region, creating rare riparian habitat in an otherwise harsh desert environment. The river flows mostly underground except for several stretches near Beatty, Nevada, and in the Amargosa Canyon near Tecopa, California, where surface water creates vital oases. With depths reaching up to 2.5 meters in some sections and a width typically less than 2 meters in the canyon stretch, the Amargosa River features diverse habitats ranging from spring-fed pools to saline flowing sections, supporting several endemic fish species adapted to extreme conditions.
