		Rock City has over 200 boulders in an area the size of two football fields. Small specks of sandy rock bonded with the calcium carbonate found in the water; they grew until they reached 9 or 10 feet in diameter and one is two stories tall. Erosion reduced the weaker surrounding material, leaving these concretions. There is no other known place in the world where there are so many giant concretions. Geologists say these Dakota Sandstone concretions were formed millions of years ago when Kansas was undersea. Early settlers would have no problem agreeing that Kansas was once under the sea because as they broke sod they found shark's teeth and found fossils in the post-rock limestone they used for homes and fence posts. Rock City has mixed memories for Debbie - she contacted her first case of poison ivy there when she was about four years old. The lower photo shows the boulder with a hole from the above photo. It has been lightened so you can see Justin, at eight years old, sitting in the hole and smiling; his white shoes out in front.
