Unique to the Hill City area is the green-gray rock, a tightly cemented sandstone from the Ogallala formation. It is not painted! This is the actual color as excavated from the earth.
One-and-a-quarter miles west of Penokee on U.S. 24 in Graham County, then 2 1/4 miles north you can see earth cuts that expose the "green rock." Look for the antique quarry equipment that marks the green-rock quarry.
In addition to the city hall, a couple of other buildings in Hill City with the green rock are the Longfellow Middle School at 203 N. 2nd and the home at 621 N. Pomeroy.
We have a great amount of geological diversity in Kansas and to know that is to "Get Kansas!"
