Check out the sinkhole in China that revealed this giant, ancient underground forest below:
George Veni is the executive director of the National Cave and Karst Research Institute (NCKRI) in the USA. He told Live Science that it comes as no surprise because southern China is home to karst topography, a landscape prone to dramatic sinkholes and otherworldly caves.
Because of local differences in geology, climate and other factors, the way karst appears at the surface can be dramatically different. So in China you have this incredibly visually spectacular karst with enormous sinkholes and giant cave entrances and so forth. In other parts of the world you walk out on the karst and you really don't notice anything. Sinkholes might be quite subdued, only a meter or two in diameter. Cave entrances might be very small, so you have to squeeze your way into them.
