Buckner Cave, Indiana

Buckner Cave can be traversed without any special equipment or rope. Many areas have a low ceiling and require crawling on hands and belly. The areas in the lower parts of the cave can be a bit muddy. It is not a high adventure cave, but it has its share of fun and thrills.  

History of Buckner Cave


Around 6 miles SW of Bloomington is 43 acres of the wooden tract donated to the National Speleological Society in 2008 by Richard Blenz. It was in 1962 that Richard had purchased the property.

Shortly, the property was thrown open for everyone who wished to visit the cave. However, since the property owner was not always present, much of the property was abused and vandalized.

In 2005 a conservancy was formed to look after the property, and cleanup efforts were implemented on a large scale. There was spray-painted graffiti, litter, and more.

A large part of the cave lies underneath the Richard Blenz Nature Preserve, and various parts and portions of the cave system extend below the other properties.  Access to the property and cave is now managed by Anmar Mirza & Dave Everton. As per existing rules, each visitor to the cave must undergo decontamination precautions to stop the onset of the dreaded White Nose Syndrome disease.

The cave is just outside a bare compound, and there are no facilities for water or a bathroom. The entrance to the cave is an oval-shaped sinkhole that is around 15 ft tall and leads you in a gentle incline that opens to a large room. If you want to access the rest of the cave, you need to crawl through a small hole for around 600 ft which opens to a large cavern. From here, cavers can explore multiple sections of the cave.  

The passageways inside the cave are generally safe, and a large section of the cave passes parallel to a running stream that is not more than 2 ft in depth. The most disturbing part of the cave is the graffiti on the walls, although the cleanup process is in operation.

If you look closely, you will notice the signature of L.V. Cushing and the date ‘1775’ hidden inside the graffiti. Vandals have destroyed many rock formations inside the cave, but Buckner Cave is still a great tunnel for exploration.
