It is located on a distinctive slumping mass composed of scree slopes, positioned beneath the breakaway ridge of one of the Alps' largest landslides, which occurred approximately 12,000 years ago following the retreat of the Rhine Glacier. The area exemplifies traditional Walser agricultural patterns, featuring patchworks of meadows that reveal historic property boundaries when differently mowed during summer. Ecologically significant, Silum contains wetland areas, dry meadows supporting rare plant and insect species, and wooded pastures that create semi-open pastoral landscapes.
