The Ibex Sand Dunes are an isolated set of beautiful sand dunes set against the backdrop of the Saddle Peak Hills at the southern end of Death Valley. The Ibex Dunes formed from sand blown east from the floodplains of the Amargosa River. The Saddle Peak Hills, a small cluster of mountains provide the stunning backdrop to the dunes; they also provide a barrier between Highway 127, and the dunes. Because of their semi-remote location, and the inability to see them from a paved road, they are one of the least visited dunes in the park. The dunes and the area surrounding them have been declared wilderness, meaning, you are not able to drive on or up to the dunes. You are free however to do the roughly 1.5 mile hike out to the them.
These otherworldly "towers," located in California's Mono Lake, may look like eerie art installations, but they occur naturally and are made of limestone. Mono Lake is a shallow salt water lake located in the high desert on the eastern slope of the Sierra Nevada Mountains, in California in the United States. The lake has no outlet to the ocean causing high levels of salts to accumulate in the waters. These rock towers form when underwater springs rich in calcium mix with the waters of the lake, which are rich in carbonates. The resulting reaction forms limestone. Over time the buildup of limestone formed towers, and when the water level of the lake dropped the towers became exposed.
