A series of landforms clustered across 97,125 hectares of southern China, with weathered shapes including tower, pinnacle, cone, natural bridges, sinkholes, gorges and cave systems, is known as what?
Karst The South China Karst phenomena are a UNESCO World Heritage site. Karst landscapes are formed in soft and water-soluble limestone, or chalk, which in south China lies on a bedrock of dolomite (a sedimentary carbonate rock, a cousin of limestone but harder); the deep layer of limestone is dissolved and weathered around its harder core or base into spectacular landscapes of sheer thin peaks, bridges or deeps. UNESCO: "The stone forests of Shilin are considered superlative natural phenomena and a world reference. The cone and tower karsts of Libo (are) also considered the world reference site for these types of karst." Inselbergs are isolated abrupt hills in virtually flat land.
