What caused the rock formations in Zion National Park?
Zion was a relatively flat basin near sea level 240 million years ago. As sands, gravels, and muds eroded from surrounding mountains, streams carried these materials into the basin and deposited them in layers.
How was Bryce Canyon formed?
Bryce Canyon Hoodoos formed over thousands of years by the same processes that form the features of surrounding parks. Water, ice and gravity are the forces at work in Bryce Canyon National Park. Joints allowed water to flow into the rock and, as water flowed through, erosion widened them into rivulets and gullies.
How were the Narrows in Zion formed?
Erosion. Uplift gave streams greater cutting force as they paved their way to the sea. The location of Zion along the western edge of the uplift caused the streams to tumble rapidly off of the plateau. As they cut into the rock layers, they carried sediment and large boulders with them, forming deep and narrow canyons.
What are the black rocks in Zion?
The varying levels of manganese and iron determine the color of the rock varnish: manganese-rich varnishes are black; iron-rich varnishes are red or orange; varnishes with similar amounts of manganese and iron are some shade of brown.

Why is it called a checkerboard cliff?
This feature’s name was officially adopted in 1935 by the U.S. Board on Geographic Names. The descriptive name stems from the cliff’s distinctive multitudinous check lines in cross-bedded white sandstone which give the impression of a checkerboard. The horizontal lines are caused by cross-bedding, a remnant of ancient sand dunes.
