Earth has gone through various changes throughout its life since the creation of the planet. Here are some of the mysterious deep holes on the earth. Most of these mysterious deep holes were created naturally.

This hole was made famous by Jacques Cousteau, who said it was one of the top scuba diving sites in the world. You can take a tour and dive in, if you’re not scared of giant, Pacific Rim monster-aliens from another dimension portaling through.

These weird, Sarlacc-pit-looking sink holes are starting to appear around the Mount Baldy Sand Dune near Lake Michigan. One sink hole even swallowed a child in 2011. Luckily, after three hours, he was dug out of the pit.

This was the hole that mysteriously appeared in Russia. It measured up to 300 ft deep and was believed to have formed due to rising temperatures. The darkening of the rim is evidence of heat during a possible explosion during the enormous crater’s creation.
