Summary

[edit]
Description

Ohio Caverns is the largest cave system in Ohio. It is located in a bedrock knob called Mt. Tabor on the southern side of the Bellefontaine Outlier (= Ohio's elevationally highest area). The cave is hosted in the Middle Devonian Columbus Limestone, which is part of a widespread shallow marine carbonate succession in eastern and midwestern America.

The dark-colored, irregular line shown above is odd - I suspect that this is a manganese oxide "wicking structure", representing staining from Mn-oxide rich groundwater percolating upward through the slightly porous rock. I am not confident that this is entirely natural. It may be semi-natural and partially related to cave trail construction (?).

Locality: Ohio Caverns, Mt. Tabor, east of the town of West Liberty, northern margin of Champaign County, western Ohio, USA
