There is a place in Siberia known as Yamal, which literally translates as "the end of the world."

It is an area that is notorious for earth-shattering events, as this was the region where the most dangerous meteor in recent history struck in 1908 with devastating results. Thankfully, the blast occurred in a relatively uninhabited zone, but forests were levelled over a distance of 2000 square kilometers (1242 miles).

Yamal is now the site of another unlikely happening in the form of a huge, unexplained crater, estimated by observers to be around 50 meters (164 feet) wide and 70 meters (229 feet) deep with water from melting permafrost cascading down its sides into snow-covered depths.

Mysterious holes are appearing across the Indiana sand dunes and nobody knows why.
What is even stranger is that the holes, which are about a foot wide and sometimes immeasurably deep, then fall in on themselves and vanish again within a day of materializing.

The local National Park Service has closed Mount Baldy indefinitely after one of the first holes swallowed up a six year old boy last July. The unfortunate child managed to escape without serious injury after remaining buried under the sand for several hours. Since then, two other holes have opened and 66 other "soft spot" anomalies have been identified across the dune.

On both sides of the border – If it were a movie special effect, it wouldn’t be believable, but it’s something real.

In the northern part of Guatemala City, a heavy storm created a huge sinkhole. Residents claim that that a three-story building and a house fell into it. 3 years ago, a similar (but smaller) sinkhole appeared in the same area. This has been going on for a while there because the town was built on top of a over a growing limestone cavern system.

John Zebrowski of the Seattle Times reports on Mel?s Hole, which is said to be a bottomless pit. The hole supposedly exists outside of Ellensburg, Washington on land once owned by Mel Waters, who says it was used for years as the neighborhood dump for trash, old appliances and even dead cattle. Dogs and birds avoided it. When the hole never filled up, Waters measured its depth by lowering weighted fishing line into it. After 80,000 feet, he gave up.

The hole is now lost. Waters says he sold the property and won’t say where the hole is. Few people know who Waters really is. Investigators believe the hole is about 10 miles west of town on a place called Manastash Ridge.
