Downstream of the swallow hole, a dry valley may occur. A sinkhole is a ground-surface depression that forms when water dissolves rock near or at the earth’s surface. This paper presents the result of an investigation of underground conduits, which connect the swallow holes and the resurgence of a blind river in the tropical, highly karstified limestone Nam La catchment in the NW of Vietnam. An example of a swallow hole in the Yorkshire Dales is Gaping Gill. Sinkholes can be natural or man-made. Chalk, a very pure limestone, is too weak and caves soon collapse. Whole streams or rivers can be swallowed up by a swallow hole but the river water can issue from a place where the stream passes into some land at a lower level. Voids can be filled and be stronger than they were before. While sink holes are more prone in central In the immediate neighbourhood of Windy Knoll these swallow-holes abound; and through them the drainage of the upland valley to the west passes into the series of caverns that underlies the limestone ridges, averaging 1600 feet high, separating it from the valley of Hope and Castleton to the east. The state sits over carbonate rock made of mostly limestone and dolostone. This raises questions of our safety in Southwest Florida and how common sinkholes are. 65 Limestone scenery dry valley forming gorge anke Swallow hotas or sink holes whero stream goats doina eddirn ane resurgunce where Wesley Chapel Gulf lies in the Mitchell Plateau (formerly the Mitchell Plain of Malott [1922]) physiographic province, a non-glaciated and karstified region developed on Mississippian limestone bedrock that has numerous sinkholes, blind valleys, swallow holes, and caves (Gray 2000)
