Rock City has about 200 rocks. That doesn’t sound very impressive until you find out these are huge Dakota sandstone concretions that are up to 15 feet high and 27 feet in diameter. The rocks were formed millions of years ago when Kansas was covered by an inland sea. They are located in a five-acre park about three miles south of Minneapolis just off of K-106 in Saline County. It became a registered National Landmark in 1978.
|Mushroom State Park|
About 45 miles southwest on another five-acre park near Kanopolis Reservoir and State Park are more unique formations at Mushroom Rock State Park in Ellsworth County. They resemble giant mushrooms and one also measures 27 feet in diameter. This park is on Prairie Trail Scenic Byway and is one of the 8 Wonders of Kansas Geography.
