Earth pyramids in the Wieser Lahn
Geological formation from the last ice age
San Genesio also boasts earth pyramids, the Wieser Lahn, near the Wieser inn. The red clay soil of the large area susceptible to landslides stands out clearly from the pastures and forests, and the earth pyramids are widely visible. The river Lahn is the source of the Rio Margherita that flows down into Val d’Adige and on to Settequerce.
