Wild Nevada - Season 4 Episode 4 Leaving Las Vegas
Overview: Dave and Chris explore sites that lie just outside of Las Vegas; including St. Thomas, flooded by Lake Mead for decades before the waters receded and the buildings reappeared. On the north edge of Las Vegas is Tule Springs Fossil Beds National Monument, and south of town they visit Sloan Canyon National Conservation Area to experience evidence of ancient visitors and a hike up Black Mountain.
