Bellevue, Ohio: Seneca Caverns - "Caviest Cave in the USA"

Open since 1933 and "retained close to its original, natural, wild state." Its entrance is out in the middle of a flat farm field, which is surprising. Has an underground river and a great catchphrase.

Seneca Caverns - "Caviest Cave in the USA"

Although it has an underground river, this cave is a fault cave. This means it was formed along cracks or faults in the bedrock. Long narrow irregular passages and none of the cave formations typically seen in caverns. Several levels to Seneca Caverns...the number of them open on a given day is dependent on the height of the water table/underground river.
