The Moenkopi Formation is a geological formation that is spread across the U.S. states of New Mexico, northern Arizona, Nevada, southeastern California, eastern Utah and western Colorado. This unit is considered to be a group in Arizona.
Thunderbird Mesa is composed of three principal strata. The bottom layer is slope-forming Organ Rock Shale, the next stratum is cliff-forming De Chelly Sandstone, and the upper layer is Moenkopi Formation. The rock ranges in age from Permian at the bottom to Triassic at the top, with a major unconformity between the sandstone and Moenkopi. The ...
The viewing of the rock formations by water is a tourist attraction in the area. The nearby city of Wisconsin Dells is the center of summer tourist activity, much of it in the form of the theme parks unrelated to the river features. The Dells of the Wisconsin River is owned by the Wisconsin Department of Natural Resources.
The Wisconsin River is a tributary of the Mississippi River in the U.S. state of Wisconsin.At approximately 430 miles (692 km) long, it is the state's longest river. The river's name was first recorded in 1673 by Jacques Marquette as "Meskousing" from his Indian guides - most likely Miami for "river running through a red place."
The geologic formations involved in the east dipping strata of the fold include the Jurassic aged Navajo Sandstone, Kayenta Formation, Wingate Sandstone, Chinle Formation, Triassic Moenkopi Formation and Permian Organ Rock Formation. The structure is the surface expression of a deep fault along the east margin of the Monument Uplift. [2]
In the park, this formation can be found in the Hurricane Cliffs above the Kolob Canyons Visitor Center and in an escarpment along Interstate 15 as it skirts the park. [6] This is the same formation that rims the Grand Canyon to the south. Farther to the west, a complex island arc assemblage formed above a subduction zone.
Adobe Mesa is located four miles (6.4 km) east of Castle Valley, Utah, on land administered by the Bureau of Land Management.Adobe Mesa is five miles long northwest-to-southeast and two miles wide, with 400-foot vertical Wingate Sandstone walls.
From 1.7 to 1.6 billion years ago granite and rhyolite emplaced in south-central Wisconsin. The Baraboo and Waterloo Quartzite in the south and the Barron Quartzite in the northwest are slightly younger, along with the slate, dolomite, conglomerate and chert included in Wolf River rocks at Rib Mountain, Mosinee Hill and the McCaslin Quartzites.
