Trona Pinnacles
Geologic Sightseeing > Trona Pinnacles (CA) 
20 miles east of Ridgecrest, California.
The Trona Pinnacles are some of the most unique geological features in the California Desert Conservation Area. The unusual landscape consists of more than 500 tufa spires, some as high as 140 feet, rising from the bed of the Searles Dry Lake basin. The pinnacles vary in size and shape from short and squat to tall and thin, and are composed primarily of spongy calcium carbonate (tufa). The Trona Pinnacles have been featured in many commercials, films, and still-photo shoots. A 0.5-mile hiking trail leads into the heart of the pinnacles for a close-up view of the spires and the surrounding desert.
From Ridgecrest, travel 20 miles east on State Highway 178 to its intersection with Trona-Red Mountain Road. Continue east on State Highway 178 for 7.7 more miles, and turn south on BLM Road RM 143. Take this dirt road for 5 miles to the site.
