Sinkhole??? It is just what it sounds like, a natural
depression or hole in the surface topography caused by the removal of soil or
bedrock, often both, by water. The size and depth of some sinkholes is
astounding, from several hundred meters deep to over 100 km across. The giant
sinkholes of Earth belong to the most impressive natural landmarks. They can
form slowly or instantly, making them all the more intimidating. Here are 10 of
the most amazing sinkholes across the world.
Berezniki Sinkhole
The expanding sinkhole first appeared in 1986 near the town of Berezniki,
Russia,
when a nearby potash mine flooded and began collapsing. It now threatens to
swallow the only rail line and support buildings in the area. The sinkhole is
about 80 meters (m) long, 40 m wide and 200 m deep. This hole may not be the
biggest or deepest, but is globally important because 10% of the world output
of potash comes from this area, and the sinkhole threatens production from this
critical source.
Bimmah Sinkhole
Bimmah Sinkhole
Making the most of one of nature's great oddities, the residents of Bimmah, Oman
turned this sinkhole into a tourist trap. (Well actually, a swim park.)
Blue Hole in Belize
Blue Hole in Belize
About 97 meters from Belize City,
there is a perfectly circular 305 meters across and 123 meters wide deep “Blue
Hole.” The hole, part of the Lighthouse Reef system, was once an opening to a
cave system during the Ice Age - it is now a magnet for extreme divers.

Mount Gambier
Mount Gambier
Mount Gambier,
the second largest city in South
Australia, is defined by many natural features,
including a massive network of volcanoes and craters, which form blue lakes
filled with artesian water and several large sinkholes. water-filled caves and
sinkholes which attract cave divers from around the globe, and such places as
Ewens Ponds, Piccaninnie Ponds, Tantanoola Caves, Umpherston Sinkhole, Cave
Gardens and Engelbrecht Cave are popular destinations f0r tourists wishing to
see and/or play in underwater sinkhole caves.
Neversink Pit
Neversink Pit
Neversink Pit, a wet limestone sinkhole in Alabama seen above in 1998, is about 15
meters deep and houses a rare species of fern. The sinkhole was bought in the
1990s by a group of cavers to preserve it for future generations.
The Devil's Sinkhole
The Devil's Sinkhole
The 400-foot deep Devil's Sinkhole in Texas
was first discovered by Anglo settlers in 1867. Today, as a registered National
Natural Landmark, the area is protected area by the state and is a well
recognized tourism destination, as well as the summer home to as many as four
million Mexican Free-tailed Bats. Apparently the bats put on quite a show in
the evenings when they leave the cave to forage, and tourists go for this show
(Evening Bat Tours) as much as for the wonder of the sink hole itself.
The Ik-Kil Cenote
The Ik-Kil Cenote
Swimmers float in the saphirre waters of the Ik-Kil cenote. The cenote locates
in the eco-archeological Park Ik Kil, just 3 km. from Chichén Itzá and Pisté in
Mexico's Yucatán Peninsula..
Called the “Sacred Blue Cenote,” it is a perfectly round well-type cenote with
exuberant vegetation and waterfalls. Cenote means “natural well” in Spanish.
The Winter Park Sinkhole
The Winter Park Sinkhole
In May 1981, during a period of record-low water levels in Florida's limestone aquifer, a massive
sinkhole opened up underneath the city's public swimming pool, which is near
the corner of Denning Drive
and Fairbanks Avenue.
In a single day the hole widened to 98 meters and to a depth of 27 meters,
destroying an import car dealership, a public pool, and large portions of Denning Drive. In
addition, the sinkhole "ate" an entire two-story home.
