Reesberg Sinkhole (HWN 214)

Highlight • Natural Monument

The spring water emerges from beneath the Bundstein sand layer and flows towards Reesberg. There, gypsum is dissolved by the small flowing currents and carried away. After several years, this created the Reesberg doline, where the water then disappears from the surface and continues to flow underground in the anhydrite.

This forest stairway leads to stamping point 214 of the Harzer hiking nobility. It is particularly beautiful here in early spring, when the wild garlic is in bloom, and the beech forest is pervaded by a delicate scent.

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.
