в Джорджии, глубиной в 179 метров
The cave and surrounding area are managed by the Georgia Department of Natural Resources and are open year-round. Due to the technical and dangerous nature of Ellison's Cave, it is generally explored by only the most experienced and capable cavers. Beginning cavers and spelunkers are severely discouraged from entering and negotiating the cave. The vertical sections of the cave require extensive knowledge and practice of single rope technique climbing, including practice on heavy ropes and in wet environments. The horizontal portions of the cave also feature technical and somewhat dangerous free climbing and bouldering environments. Careful preparation, including bringing the proper gear and clothing, is essential.
