Organ Rock Formation Organ Rock Formation The Organ Rock Formation or Organ Rock Shale is a formation within the late Pennsylvanian to early Permian Cutler Group and is deposited across southeastern Utah, northwestern New Mexico, and northeastern Arizona. This formation notably outcrops around Canyonlands National Park, Natural Bridges National Monument, and Monument Valley. The age of the Organ Rock is constrained to the latter half of the Cisuralian Epoch by age dates from overlying and underlying formations. Important early terrestrial vertebrate fossils have been recovered from this formation in northern Arizona, southern Utah, and northern New Mexico. These include the iconic Permian terrestrial
Lemon squeezer (rock formation) grow on top of a thin rock ceiling above the path. Lemon squeezer (rock formation) The Lemon Squeezer is an unusual rock formation in Harriman State Park, New York. It is located at the intersection of the Appalachian Trail (White) and the Arden-Surebridge Trail (Red Triangle), near the base of Island Pond Mountain in the town of Tuxedo. The trail initially passes under a large boulder resting on top of other rocks. After passing this point, the nature of the Lemon Squeezer becomes apparent as the hiker gets "squeezed" through a path that is high, wide, and angled 15 degrees.
