Part of the Smoky Hill region in the north-central part of the state, the Dakota formations are the remains of beach sands and sediments of the Cretaceous Period, the interval of geologic time from about 144 to 66 million years ago. Sanstone and sedimentary rock, is held together by natural cement. The concreations that make up Mushroom Rocks are cemented calcium carbonate. The largest rock measures 27 feet in diameter.
Shelby S. on Mushroom Rock Trail
Nice little trail, good if you or your dogs need to stretch your legs. A very short trip on a dirt road right off of highway 140 or if leaving Kanopolis Lake you can get to it from highway 141 too. I live close by & my dogs just love going out there. There is poison ivy, make sure kids know what it looks like.
I was not too impressed. It's a very small park. I was able to walk the whole trail area in 15 min. The rocks formations are cool but I would suggest just looking at a picture online and save yourself the trouble of the dirt roads. There is one bench and one picnic table. Pit vaults available.
