Digital elevation model of the Ruinaulta (Vorderrhein). The most probable location of the ancestral dam extends in a E-W direction across the gorge. Three outcrops of delta deposits are found upstream of the dam at 820 m a.s.l. (Tuora and Planezzas) while the deposits of the Ransun fan downstream of the dam are located at less than 800 m a.s.l
