Karren (Inventory)/Rillenkarren

From LagWiki

The Rillenkarren field is used to record stations that exhibit rillenkarren.

Rillenkarren are etched flutes or channels which are dissolved by dripping or flowing water. They usually exhibit as parallel columns of flutes. The hollows or "rills" may narrow and disappear with distance or, when dissolved by acid rich water like in the Guadalupes, may become deeper with distance. This latter type should probably be called "rinnenkarren" because of this characteristic but for purposes of the Carlsbad Cavern National Park Cave Inventory Form, they are inventoried in this field.

Rillenkarren may form on soft materials like guano or sediments. They can also form in harder materials like bedrock or massive gypsum. The definining characteristic is multiple channels separated by ribs of undissolved material.
