#5: Black Crack
This Black Crack is so big and so deep that it’s been known to cause vertigo just looking at it. That’s some serious canyon crack! And the craziest part is that it’s still growing. Scientists estimated that it’s widening by about 1 inch every year. You should definitely take care when visiting it.

Don’t lean too far over the edge, and don’t drop any valuables there. You might never see them again! Thankfully, it’s not the deepest fissure in the world. That award goes to the Almannagjá fissure in Iceland. It stretches for around 25 miles and is up to 98 feet deep.
