The rim top layer is the Kaibab Limestone Walnut Canyon, Flagstaff Arizona. The Kaibab Limestone was named by Darton [4] in 1910 for the Kaibab Plateau, which is on the north side of Grand Canyon in Coconino County, Arizona. In his definition of the Kaibab Limestone formation, no type locality was designated. He also designated the Kaibab ...
The Middle Permian Toroweap Formation is a thin, darker geologic unit, between the brighter colored units of the Kaibab Limestone above, and Coconino Sandstone below. It is a prominent unit in Grand Canyon, Arizona, Southwestern United States, found through sections of the South Rim, Grand Canyon, and the North Rim, of the Kaibab Plateau; also the Kaibab's southeast extension to Cape Royal ...
Brady Canyon is a cliff-forming gray limestone with some chert. Wood Ranch is a slope-forming pale red and gray siltstone and dolomitic sandstone. An unconformity marks the top of this formation. One of the highest, and therefore youngest, formations seen in the Grand Canyon area is the Kaibab Limestone (see 6d in figure 1).
Later in Permian time, the Kaibab Sea invaded the land and laid down a limey ooze that later lithified to form the locally up to 200 foot (60 m) thick Kaibab Limestone. [8] This is the same light gray to white formation that rims the Grand Canyon to the southwest (see Geology of the Grand Canyon area).
The geology of Tennessee is as diverse as its landscapes. Politically, Tennessee is broken up into three Grand Divisions : East , Middle , and West Tennessee . [ 1 ] Physically, Tennessee is also separated into three main types of landforms: river valley plain, highlands and basins, and mountains.

The topmost layers over which the lava flowed, the Kaibab Limestone, was deposited in Early Permian time, around 290 million years ago.

As seen in the above photograph, Fossil Mountain exhibits a large cliff of Kaibab Limestone. The southwest slope of Fossil Mountain is a highly vegetated (trees), and high angle slope to the prominence. Below the 350 ft (110 m) cliff of Kaibab Limestone is about ~250 ft (76 m) of vegetated slope-forming Toroweap Formation.
