Natural History Wanderings

The remnants of Tropical Storm Mario brought 0.6 inches of rain to Furnace Creek on the night of September 18—about one-quarter of the park’s average annual rainfall in just a few hours.

In a desert like Death Valley, even small amounts of rain can trigger flash flooding. The park’s rocky, steep terrain causes water to run off quickly, creating fast-moving flows of mud, rocks and debris. These floods have covered some roads and have eroded road shoulders, making travel hazardous.

Roads currently closed due to storm damage:

Badwater Road

North Highway

West Side Road

Twenty Mule Team Canyon

Cottonwood–Marble Roads

Mustard Canyon

Keane Wonder Mine Road

Still open:

CA-190, Daylight Pass and Dantes View

Unpaved roads may be impassable due to mud or erosion. Park staff are assessing conditions, and more closures may be announced. Proceed with caution and be prepared to self-rescue.
