Monument Rocks. Oakley, United States

Rising out of the vast, flat prairie like alien sculptures, the striped Monument Rocks stand 80 feet high. Made of chalk, these formations were shaped 80 million years ago when an ocean covered Kansas. Although water helped create these rocks, water is also erasing them from the landscape because the chalk erodes easily. Each year the keyhole arch is a slightly different shape because of weathering.

To get to Monument Rocks, leave I-70 at exit 76 near Oakley. The site is 25 miles southeast via US 83 and dirt county roads
