These rock formations are about 20 miles southeast of the town of Oakley. Just before turning off the dirt road, which leads to the formations, we stopped at an old restored stone building. A sign by the road said it was the Keystone Gallery, an art gallery/fossil museum. I grumbled a bit about making the stop, as I just wanted to see Monument Rocks. It turned out to be a very informative stop, however! Barbara Bonner, who owns the museum with her husband Chuck, greeted us warmly and was very eager to share with us their stories of fossil hunting in the surrounding area. The land having the fossils covers two counties of Kansas. We saw some of their collection of fossilized ancient fish which they have found over the twenty some years they have had their museum. Chuck's primary occupation is painting and his work is also displayed in the museum. Barbara and I also discovered that we both have sons, of of the same age, out on the west coast and in the gaming industry. Despite that rather long stop we did make it out to the rock formations. The wind-carved and water-eroded limestone towers average about 70 feet in height. The site can be described best as a many layered ancient Cretaceous seabed sitting on a semi-arid plain.
