Trona Pinnacles
A series of otherworldly rock spires, some as tall as 140ft. These pinnacles formed on the lakebed when calcium rich springs interacted with minerals in the lake from as long ago as 100,000yrs to as recent as 11,000 years ago. Similar processes are still occurring today in Mono Lake, an incredibly alkaline (the opposite of acidic) lake ~200 miles north of here.
