What is a Sinkhole Landform?

A sinkhole is a hole in the ground caused by the collapse of underground soft rock formations.




How are Sinkholes Formed?

Sinkholes are usually caused by moving groundwater below the surface that dissolves limestone or other soft rock formations, causing them to collapse and form a hole in the ground.

How Large is a Sinkhole?

Sinkholes have been found that are from 3 feet across to over 2000 feet in diameter.

Where can a Sinkhole be found?

Sinkholes can be found where underground limestone or other soft rock formations exist and there is substantial ground water movement.

What are Cenotes?

Cenotes are sinkholes in an area where the water table is very high, so that groundwater is visible in the hole, sometimes forming a lake or pool near the surface.

The world’s deepest known sinkhole is called Xiaozhai Tiankeng and is located in the Chongqing Municipality of southwest China. It is 2151 feet deep and more than 2000 feet across at the surface. Well known to local people, it was discovered by researchers in 1994.

Sima de las Cotorras is a very large sinkhole 520 feet wide and 460 feet deep and is known for having thousands of green parakeets that live in the trees that grow at the bottom of the hole. There are also 80 other species of birds and hummingbirds living among them. About half way down on the sides of the hole there are ancient paintings estimated to be from 5,000 to 10,000 years old.
