Headwaters of the Amargosa
The Amargosa is one of the world’s longest underground rivers. For 185 miles, it flows largely unseen through parts of southern Nevada and southeastern California, except where it occasionally surfaces to create ecologically rich oases.
Ash Meadows National Wildlife Refuge
In a remote corner of southern Nevada, groves of ash and mesquite trees shelter spring-fed pools of warm, crystal-clear water that are a boon for native wildlife, some of which are rare and found nowhere else on Earth. This unexpected fertile patch—Ash Meadows National Wildlife Refuge—is where the desert springs to life.
