The Jurassic Period began 180 million years back, creating the sheer cliffs and ledges of the Kayenta Formation, famous for their black and gunmetal-blue streaks of colour or "desert glaze." for the duration of this point in geologic time, an additional series of formations was created. The Morrison Formation consists of stonework, sandstone, and mudstone deposited by rivers flowing into the area. The Estrada Formation, which is made of Estrada Sandstone, appears in the Wahweap area as white-coloured rock, although it is more usually creamy-yellow paint. The peak of Castle Rock is an excellent illustration of Estrada Sandstone. The Morrison and Estrada formations make up Castle Rock and Tower Butte. The Carmel Formation, with its level, maroon-purple-brown beds, is seen along Lakeshore Drive, among Glen Canyon Dam and Wahweap. Navajo stonework is the leading configuration found in Lake Powell and is made from sand dunes that were hardened by force from deposits on top of them. The deposits finally wore away and exposed today's sandstone. Other layers include sea deposited sediments or fossils of earth or marine organisms that lived millions of years back. Fossil wood and fossils of dinosaur bones along with ocean shells and tiny sea creatures can be found in some rock strata in this region.
The Cretaceous Period began 135 million years back and formed three types of rock in Glen Canyon. Straight Cliffs Sandstone which makes up the perpendicular cliffs that make bigger to the north; Tropic Shale, which has lots of fossils of oysters, snails, sharks, and other sea being that once lived in a sea in the area; and Dakota Sandstone, composed of various rock types, counting coarse stonework and conglomerates.
By the way of summing up, Lake Powell is one of those magnificent places to visit that gets under your skin and for no reason leaves you. Lake Powell is one of the Southwest's finest loch hobby areas and continues to be discovered annual by more and more holiday- makers.
