This is the roof of an underground river or a cavern that is connected to the ground surface and allows sunlight to shine in. It is usually a vertical shaft-like channel that reaches the ground surface. Viewed from the cavern bottom, this feature looks like a transparent skylight akin to that in a house. Karst windows vary in size and form. The karst window of the Fuming Cave in the Dashiwei karst window cluster in Leye, Guangxi Province, has an area of 16.5 m 2 and a depth of 365 m. Sunshine can reach the cave chamber, so it is also called ‘Sunshine Hall’. In the Sanmen karst window cluster in Fengshan, Guangxi Province, there are four windows along a 690-m stretch along a subterranean river, and three are accessible by boat. Therefore, this site is also called the ‘Sanmen (Three Doors) Sea’ (Fig. 26).
