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.
One of the most recognized landmarks in Zion National Park, Court of the Patriarchs reach into the Utah sky. These three photogenic peaks bear the biblical names of Abraham, Isaac, and Jacob. Towering above Birch Creek Canyon almost 2000 feet, the Court of the Patriarchs represents nearly a full layer of Navajo Sandstone. This exposed sandstone is one of nine Zion rock layers that together span 150 million years of sediment deposits. The Patriarch cliffs represent one of the thickest layers of sediment, making up some of the tallest cliffs in the world. Occasional flash floods in the Virgin River increase water volume by 100 times and bring down tons of loose rock and sand, scouring out new side canyons and re-channeling the river. Here in Zion Canyon this magnificent scenery is always experiencing change, but its subtleties are seldom recognized in such an immense canyon.
