The Reesberg doline lies on a geological boundary between the Bunter sandstone and the anhydrites of the Zechstein. The spring water emerging from the Bunter sandstone is very clear and therefore has a high dissolving potential. It can absorb up to two grams of gypsum per liter and then flows underground.
