Titus Canyon is a deep gorge in the Grapevine Mountains on the east side of Death Valley, valued for uniting striking geology, desert ecology, Native American heritage, and mining history. Although the mountains rose relatively recently, the canyon exposes rock more than half a billion years old, including Cambrian limestone formed when this region lay beneath tropical seas and later folded into complex shapes. Timbisha people left petroglyphs near springs that sustained travel and life in the desert. In the early 20th century, nearby Leadfield briefly boomed on exaggerated mining hopes before becoming a ghost town, while desert bighorn sheep and native plants still characterize the canyon today.
