Thunderhole Nature Preserve

KEY STATS

LOCATION
Putnam County, Tennessee
YEAR ACQUIRED
2020
LENGTH

In 2020, the NSS signed a Memo of Understanding to re-open a classic TAG pit to experienced cavers. The 129-foot pit is formed at the Hartselle-Monteagle contact and during rainfall, a waterfall occurs the full length of the wall opposite of the entrance and disappears into the floor. Thunderhole has been dye-traced to caves in Hidden Hollows Springs. The amazing generosity of the landowner allows cavers to enjoy access and helps the NSS with our mission of education, exploration, and conservation of caves.
