Dive the Billion Gallon Underground Lake, Bonne Terre Mine with SCUBASTOP this February, 2020.
Missouri is the location of the world's largest subterranean lake. Explore beneath the surface with a fun group and experienced guide. Dive sites begin already about 50m below the ground, then you have the option of over 24 trails in an underground lake the size of a small town! Conditions are surprisingly great, with around 14°C water and at least 30m of visibility.
Diving at Bonne Terre begins with a map-assisted briefing and safety video. First-time Bonne Terre divers must dive on Trail One first, and a portion of this dive is devoted to standard checkout procedures such as mask-clearing and air-sharing. Trail One is an exhilarating dive with loads to see and explore, including 70m rock pillars, huge archways, an elevator shaft, staircases and structures, slurry pipes, calcium formations, ore-carts and other mining tools and artefacts.
