The One-mile Loop trail descends 300 feet into Devil’s Punchbowl Canyon to Punchbowl Creek. As you descend you will notice the huge sedimentary sandstone formation is tilted vertically from its once horizonal position. The Punchbowl Formation has been compressed and tilted by the collision of the Pacific Tectonic Plate with the North American Plate north and east of the San Andreas Fault. As the two plates collide the Pacific Plate is compressed and forced up along two faults. The Punchbowl Fault to the south is pushing up the 8,000-foot San Gabriel Mountains. The Pinyon Fault on the north is pushing up Pinyon Ridge. The Punchbowl sandstone has been warped into a “V” shaped syncline due to these great pressures. Notice the sandstone slabs on the south are tilted up with the San Gabriel Peaks while the slabs to the north have been tilted up with Pinyon ridge.
