Doug descends into California's Death Valley and climbs high into the wilderness mountain ranges of Nevada, before descending into another far-flung basin.

About Doug's Geology Journal:

In the new five-part series DOUG'S GEOLOGY JOURNAL, field geologist and host Doug Prose helps make sense of complicated geologic stories.

By sharing his observations in places as diverse as Iceland and Death Valley, Doug explains big-picture geologic processes that shape the landscape.

Throughout the series, he shares his observations as he treks over desert terrain, climbs hills, squeezes between rocks, and contemplates geological features while sitting in a hot spring.

He visits the volcanoes of Iceland; the red rock country of Utah and Arizona; the jagged trace of California's San Andreas Fault; the valleys and mountains of Nevada; and the complicated terrain of Sicily.

This series is sure to inspire interest in not only the geology around us, but the amazing stories that are shaped by planet Earth.
