Karst Publications & Maps

Karst Publications & Maps

The ODNR Division of Geological Survey has been mapping karst in Ohio since 2011 and has produced numerous publications and products to illustrate where and how karst forms in Ohio. Such research enables the Division to provide information to industry, government agencies, and the public at large for use in land-use planning and mitigating the impacts of karst on groundwater, infrastructure, and commercial and residential buildings and other structures.

These publications and products are available using the links in the sections below. For more information on karst formation in Ohio, visit the Sinkholes & Karst Geology webpage. 

Recent Reporting

2019 Karst Annual Report: Karst at the Silurian-Devonian Contact in South-Central Ohio – The report includes notable features and unique characteristics of the study area, predominantly in Adams and Highland Counties, along with an updated summary of the statewide status from 2009 until now. This report marks a transition away from traditional mapbooks to a streamlined report of the fieldwork season that can be used in conjunction with our interactive web map.

Karst Interactive Map

Released in 2019, the Karst Interactive Map is a record of karst features found throughout Ohio that is updated regularly as mapping continues. Each datapoint links to a list of information about the feature, including location; feature type; notes and comments about the location or feature; and photograph(s), if available.

For detailed information about specific karst features or to check your location of interest for karst features, input the address information into the Address/Coordinate Search menu, and then click on the feature of interest. Also, the current Ohio karst GIS dataset can be downloaded (for use in GIS) via the introduction screen that appears when the map is first launched.
