Geological and Lithological Profile
The Müllerthal is a geological system characterized by Lias-era sandstone formations. The terrain is defined by extreme fluvial erosion, resulting in vertical rock faces and narrow canyon structures. This landscape serves as a primary scientific reference in the Grand Duchy, supporting high biodiversity.
Hydrological Systems
The Black Ernz river governs the hydrological dynamics of the Müllerthal. Erosion has created landmarks such as the Schiessentümpel. Regional management prioritizes the maintenance of the 112km trail network while preserving the structural integrity of the fragile sandstone clusters.
