New Acquisition: Shawnee Karst Preserve Extension. The IKC has recently completed fund-raising for a 17.5-acre extension to our Shawnee Karst Preserve in Lawrence County. Donations continue to be accepted and will be used for acquisition of additional properties. Click here for more information.

Covid-19 Update: IKC preserves are currently open. We have reduced the maximum group size to 10 for cave trips and are limiting trips to 1 per day. Cavers are asked to maintain physical distancing and follow CDC guidelines. Click here for details.
