Hoodoos in mud

The Silt Hoodoo field of the Silica section should be used to record any observations of hoodoos in silt or other granular media.

Hoodoos are formed in relatively soft rock or sediments topped by a harder, less easily eroded cap that partially protects each column. The softer material is partially eroded leaving behind a column. The result is a tower or cone of the more easily eroded material capped by the protecting layer.


Silica (Inventory)/Silt Hoodoo is a part of the cave inventory project.
