The sand dune environment is not conducive to the preservation of fossil bones, but dinosaurs did wander over the dunes, leaving behind numerous trackways. Here and there, fresh-water oases left behind deposits of limestone that contain a fossil record of crocodiles, small dinosaurs, and other smaller creatures.
The sandstone of the Navajo is quite porous and the underlying Kayenta Formation is not. Water percolates through the sandstone, and when the Kayenta/Navajo contact zone is exposed, springs often flow. The much visited Weeping Rock, with its hanging gardens of ferns and flowers is one of these springs.
Zion is a beautiful place...
An added thought in terms of perspective. The incredibly steep and tall looking Angel's Landing in the photo at the top can also be seen in my last post, from Observation Point, which is on the rim of Zion. In that first picture, Angels Landing is the flat bench-like cliff in the center right of the photo. The cliff has the shadows on it. Observation Point is a tough hike, almost twice the climb of Angel's Landing, although there are no chains on top of vertical cliffs to give one that feeling of vertigo...
