About the Ohio Cave Survey, Inc.

The purpose of the Ohio Cave Survey is to study, map, and document the caves and karst regions of Ohio. The "Ohio Cave Survey" (OCS) was originally founded in 1952 by Roger McClure, Phil Smith, and the Central Ohio Grotto. It was later managed by the late Dr. Horton Hobbs, III, who maintained the records at Wittenberg University.

After Dr. Hobbs retired and moved from Ohio, the records were transferred to the Ohio Department of Natural Resources, where they have been maintained. The Ohio Cave Survey, Inc., a non-profit corporation of Ohio, was formed in June, 2020, to carry on and expand on the work started by Dr. Hobbs, III. Later in 2020, the OCS, Inc. was granted 501(c)(3) federal tax-exempt status by the IRS.

The OCS archives contain cave maps, survey notes, exploration photos, descriptions, GIS files, and many other forms of information. We only share data with cavers, landowners, and other agencies who submit a legitimate request for information. All requests for information and data are reviewed before the records are released. Please contact us to request information. The policy for release of records and the application process are being developed at this time. Cave locations will not be given out without a specific, legitimate reason.
