Rockhounding Kansas

Kansas is a good state for rockhounding.  Although the state does not even have an official rock, stone, gemstone, mineral, fossil, or dinosaur, Kansas does have many fossil-bearing rocks at the surface, mostly limestone, sandstone, and shale.  Most limestone (in Kansas and elsewhere) was deposited in warm, shallow seas, such as the ones that covered Kansas intermittently during the Pennsylvanian, Permian, and Cretaceous periods.  These warm, shallow seas were not only good for making limestone, but also for preserving the organisms that lived in these seas.  The calcium carbonate ooze that collected on the sea floors made a perfect burial ground.  Accordingly, Kansas’s limestone contains many fossils.

State Rocks, Gemstones, Minerals, Fossils, & Dinosaurs

Kansas is the only state that has not designated any official rock, stone, gemstone, mineral, fossil, or dinosaur.

Museum - Post Rock Museum

Post Rock Museum
LaCrosse, Kansas
The Kansas pioneers encountered an area without extensive forests and a lumber supply.  But, Kansas has limestone that could be used to construct buildings.  In fact, the limestone formation is just about right for building stones and posts.  When limestone is first exposed it is soft and chalky, making it easier to drill and cut.  Once the stone has been exposed to air, however, the edges become hard making it an exceptional building material for the plains pioneer.  The Post Rock Museum includes an authentic stone quarry re-creation illustrating the methods used to cut posts for fencing as well as tools and items depicting the history of the post rock unique to this region.

Kansas Meteorite Museum & Nature Center

Places to Visit - Interesting Sites To See

Site - Monument Rocks

Monument Rocks National Natural Landmark
Gove County – Western Kansas
Monument Rocks (also known as Chalk Pyramids) are a series of large chalk formations that were formed about eighty million years ago when the area was part of a vast inland sea.  Some of the Niobrara Chalk formations reach heights of seventy feet.


Site - Castle Rock (in 2005)

Castle Rock
Gove County – Western Kansas
Castle Rock (located about twelve miles south of Interstate 70 between Quinter and Collyer, Kansas) is a large limestone pillar in the Smoky Hills region.  The formation is about seventy feet tall.  The formation served as a landmark on the Overland Trail.  The formation is fragile and may not last many more years.  The tallest spire fell following a thunderstorm in 2001.


Site - Mushroom Rock State park

Mushroom Rock State Park
Smoky Hills Region Near Marquette, Kansas
Mushroom Rock State Park is well known for its mushroom rock formations.  These formations were formed through a process of nonuniform erosion and weathering in which a hard mass of Dakota Sandstone resisted erosion while the underlying softer stone weathered away, forming a "mushroom" shape.  There are two mushrooms and a giant shoe rock, as well as numerous other rock formations in the park.


Site - Rock City

Rock City
South of Minneapolis, Kansas
Rock City is a public park that contains three clusters of approximately two hundred huge Dakota Sandstone ‘cannonball’ concretions.  The concretions range in size from about ten to twenty feet in diameter.  The site is a designated National Natural Landmark.
