  1. The difference between a beautiful sinkhole and a dangerous one is probably dependent entirely on its location. Some areas, such as parts of Venezuela and Mexico, draw tourists to their scenic sinkholes. In Mexico, pools called "cenotes" are really sinkholes that have filled with water and are surrounded by lovely vegetation. The famous Sarisarinama sinkholes in Venezuela are known for their almost perfectly circular shapes - - each one measures about 1,000 feet (305 meters) wide. They are perched atop high mesas in the Tepui region of Venezuela.

    The Qattara Depression in Egypt is the Earth's largest naturally occurring sinkhole. It measures 436 feet (133 meters) deep, an astonishing 75 miles (120 kilometers) wide and 50 miles (80 kilometers) long. The British used the difficult terrain in the depression during World War II as an important defensive border. Today, it is one of Egypt's many tourist attractions. Some are looking for ways to use the Qattara Depression in the search for clean energy. The thought is if the depression gets filled with water, its low elevation and water evaporation could be used in a hydro-solar system.

    The Dead Sea, along the border between Israel and Jordan, is already the lowest point on Earth. It sits 1,371 feet (417 meters) below sea level. The water has an extremely high salt content. The water level of the Dead Sea is dropping because of mineral mining and increased water use. As a result, the newly uncovered ground is riddled with sinkholes. As salt deposits break down, they erode the earth and destabilize the ground, creating the perfect conditions for sinkholes. Some of the solutions suggested are to connect the Dead Sea to either the Mediterranean or Red Sea to once more increase water levels. At least one scientist believes the erosion will end once the water level stabilizes - - this will happen when the water's salt content becomes so high that it can't evaporate [source: Anderson].
