In the southern portion of China there is an expansive karst landscape, formed by the dissolution of soluble rocks such as limestone, dolomite, and gypsum. The region is home to the South China Karst UNESCO World Heritage Site, which is actually seven different notable features, as well as the visually impressive Moon Hill, some of China's supercaves, and Xiaozhai Tiankeng, the world's deepest sinkhole. You can climb Moon Hill, but it's best to plan ahead. You can also explore China's great caves, but it is necessary to explore between October-November and February-March to avoid the monsoon seasons, and getting down Xiaozhai Tiankeng requires a lot of gear. You can read more about the Tiankengs (giant dolines or sinkholes) in the karst of China (PDF).

The London Geographical Journal, the preeminent publication in its field, observed in 1953 that “Fawcett marked the end of an age. One might almost call him the last of the individualist explorers. The day of the aeroplane, the radio, the organized and heavily financed modern expedition had not arrived. With him, it was the heroic story of a man against the forest.” Fawcett was none other than Percival "Percy" Harrison Fawcett, British soldier, trained as a surveyor of unknown lands, doubling as a British spy. But his true love was exploration, and not simply to mark boundaries on a map. His final goal was the same that had been the demise of many explorers: a mighty lost civilization in South America.
