Global InformationPanhole information
A panhole is a depression or basin eroded into flat or gently sloping cohesive rock.[1] Similar terms for this feature are gnamma[2] or rock holes[3] (Australia), armchair hollows, weathering pans (or pits) and solution pans (or pits).[1][4]
Some authors[4] refer to panholes also as potholes, which is a term typically used for similarly shaped riverine landforms. In fluvial geomorphology, the term pothole is typically used for a smooth, bowl-shaped or cylindrical hollow, generally deeper than wide, found developed in the rocky bed of a stream. This type of feature is created by the grinding action either of a stone or stones or of coarse sediment whirled around and kept in motion by eddies or the force of the stream current in a given spot.[5]
