Meseta de Sarisariñama

The Sarisariñama is a tepuy in the Jaua-Sarisariñama National Park in the extreme southeast of the Bolívar state in Venezuela, near the border with Brazil.This plateau is one of the most isolated in the country, being hundreds of kilometers from the nearest highway. Currently access is restricted to scientific researchers only. The most distinctive and peculiar feature of this 2,300-meter-high tepui is the presence at its top of practically circular cavities (chasms) that are still a mystery to geology today. These deep depressions have a diameter at the mouth of 350 meters, and a vertical depth of 350 meters as well.
