In the Upper Engadine and the Maloja Pass area the Engadine Line is represented by long northeast-trending fault segments and long east-west trending fault segments which form scarps. Depressions located between the fault traces are occupied by lakes such as Silsersee, Silvaplanersee and St. Moritzsee, which do not appear to be moraine-dammed and may have been formed by the activity of the Engadine Line. Close to the Maloja Pass the Engadine Line forms a single fault. In the Forno Valley, the fault crops out in the form of polished surfaces, scarps and striations along with fault gouge. The course of the Orlegna River is diverted by a shutter ridge at the intersection with the Engadine Line. There, the Engadine Line runs along the southern side of the Inn and Bregaglia Valleys and is accompanied by deep-seated mass failures; eventually it disappears under sediments and close to Promontogno. As with the Inn Valley, the Bregaglia Valley is the surface expression of the Engadine Line.
