World's Largest Cluster of Sinkholes Discovered
Who says we're done exploring the Earth?
Scientists in China announced a major new discovery this week: 49 massive sinkholes that were previously unknown, representing the highest natural density of the phenomenon in the world.
Government researchers discovered the sinkholes during the course of a four-month survey in the Qinling-Bashan Mountains, which are located in the Hanzhong area of northwest China's Shaanxi Province.
The 49 sinkholes are clustered in a 230-square-mile patch of land within the 2,000 square miles that were surveyed.
