Tower karst

Tower karst are tall rock structures made up of soluble rock such as limestone.

Tower karst forms as near-vertical joints and fractures are eroded downward by solution, leaving parts of a previously coherent rock mass isolated from each other.

[1] Tower karst is most common in tropical regions,[1] although it may form in other climates as well.

[2] Examples include Khao Phing Kan, also known as James Bond Island, in Thailand, and Cat Ba Island in Vietnam.
