@journeyunrestrictedusa: Ever driven through Cajon Pass and wondered how those giant tilted rock walls formed? 🪨 Mormon Rocks preserves roughly 12–16 million years of geological history. Ancient stream deposits hardened into sandstone and conglomerate before fault-related movement tilted the layers skyward. The landmark’s name connects to the historic Mormon Road and the passage of approximately 500 Mormon pioneers through Cajon Pass in 1851. Today, visitors can explore the formations on an easy 1.03-mile interpretive loop just west of I-15 along State Route 138. 📍 Mormon Rocks, San Bernardino County #MormonRocks #CajonPass #SanBernardinoCounty #CaliforniaTravel #CaliforniaHistory
