List of National Natural Landmarks in West Virginia facts for kids

This is a list of the National Natural Landmarks (NNLs) in West Virginia. There are fifteen in all — five are wetlands (such as bogs and swamps), three are forests, six are limestone caves/karst, and one is a rock formation. All are located entirely within West Virginia with the exception of the Cranesville Swamp Nature Sanctuary, which lies mostly within Garrett County, Maryland but also extends into Preston County, West Virginia. Ten of the fifteen NNLs are within the boundaries of the Monongahela National Forest, although this does not necessarily mean they are on public land.

De-designation

According to a notice in the Federal Register in July 2006, Swago Karst Area in Pocahontas County was removed by the Department of the Interior from NNL designation in response to owner requests. It was originally designated in November 1973. Its description formerly read: "A classic illustration of features associated with karst topography and terrain, including caverns and other passages."
