Why can’t you swim in a blue hole
For starters, most of the old mines lack proper beaches. Swimmers need only to wade in a few yards before they find themselves in water that can run to depths of 50 to 100 feet. Those depths result not only in currents that can take even strong swimmers by surprise, but also cold temperatures that cause muscle cramps.

"That means that below the H2S, there's no oxygen and anything that falls down there now is preserved. "Without oxygen, nothing survives. Beneath the hydrogen sulfide layer it is very dark.
