[edit]DescriptionGreat Unconformity Up close - Flickr - brewbooks.jpg |
There is about a 1.2 billion year gap in the rock - that is the Great Unconformity,, and this hike provided an excellent view. "Powell's unconformity in the Grand Canyon is between the Tapeats Sandstone of Middle or Lower Cambrian Age, about 500 million years ago, and igneous and metamorphic rock of the Statherian Period of the Paleoproterozoic Eon, around 1700 million years old, give or take a few hundred million years, with a gap of over a billion years.
