Karst Interpretive Site
The Harmony Visitor
Center is open to the
public from April through
October. Inside the
visitor center, one can
explore exhibits about
karst and see fossils
found in the area. A short
hike on the Harmony-
Preston Valley State
Trail, which starts right
behind the visitor center,
leads to the Harmony
Karst Interpretive Site. The sinkhole, highlighted at the site, is a
good example of the unique geological make-up of southeastern
Minnesota. Three drainage holes are featured as a point of interest
with a viewing deck located above them. There are also several
educational signs located throughout the sinkhole, explaining the
geology of the sinkhole, how it was formed and why it is important
to protect sinkholes and keep them clean.
Karst geological areas are rare, with one of about four being
located here in southeastern Minnesota. Other areas of similar
geology are located in Missouri, Florida and Kentucky.
In a karst geological area, the limestone is very close to the
surface, and heavy rain and moisture can cause the limestone to
collapse, making a sinkhole.
