World's Deadliest Water Bodies

Horseshoe Lake, situated near the town of Mammoth Lakes, California, is a silent killer. It is beautiful yet deadly, and at its north end there are few trees or signs of life visible. Carbon dioxide is present at 95 times its normal quantities in the soil.

A way to show the effect of this is to dig a hole in the sandy earth and then hold a flame inside it. It will extinguish right away as there is not enough oxygen. This has a deadly effect on humans. In the town or any windy area it often disperses, but in the lake itself and some areas surrounding it, it doesn’t.

 In 2006, three people were killed by the CO2 build up in a cave not far from the lake where they took shelter. It is a frightening case of out of the frying pan, into the fire.
