have historically given names to the strange forms. These ancient spires were once dubbed "Cathedral City". Geologically, the pinnacles are classified into four general shapes. Towers are taller than they are wide and rise . Tombstones are stubby and squat and rise . Most tombstones are in the northernmost tufa formations. Ridges are massive toothy tufa ruins. Trona has three ridges, one in the northern tufa cluster and two in the middle group. One ridge is long and wide and tall. Cones are less than tall. Dumpy and mounded, cone shapes lie scattered throughout the Trona Pinnacles. In Media The Pinnacles are recognizable in more than a dozen hit movies. Over thirty film projects a year are shot among the tufa pinnacles, including backdrops for car commercials and sci-fi movies and television series such as Battlestar Galactica, Star Trek V: The Final Frontier, Disney's Dinosaur, The Gate II: Trespassers, Lost in Space, and Planet of the Apes.
