The Bookcliffs

The top layer of rock on the Bookcliffs is Mesa Verde Sandstone and the side slopes are Mancos shale.

There are fossils in the Bookcliffs, but they are mostly at the base. These are mostly ammonites, or early mollusks. They are animals with a hard shell and no vertebrae.

Nodules are rounded lumps of a mineral or a mixture of minerals surrounded by softer rock and sediment. Basically, they are large concretions. Nodules range from one foot to six feet in diameter. There are both concretions and nodules within the layers of dark grey limestone in the Bookcliffs. Other rocks and minerals found in the Book cliffs include; agate, jasper, and petrified wood.

In the Bookcliffs by I-70 there are the rocks sandstone, shale, siltstone, limestone, and coal. But not all of the Bookcliffs have coal. The discovery of coal was first found on the Bookcliffs in only a two mile large stretch.

The Bookcliffs also have many things to be mined and drilled for. Coal, has and still is being mined. But oil and helium is being taken from the Bookcliffs as well.



Wildlife The wildlife in the Bookcliffs are; black bears, antelope, lizards, other reptiles, amphibians, rocky mountain elk, sage grouse, hawks, golden eagles, bald eagles,bison and moose occasionally, cougars, Rocky Mountain bighorn sheep, and many other small mammals and birds.
