The Tödi, the highest of the range and of north-eastern Switzerland (3,614 m), is attended by numerous secondary peaks that arise from the extensive snow-fields surrounding the central mountain. A very considerable outlyer, whose chief summits are the Schärhorn and the Gross Windgällen, belonging to the canton of Uri, is connected with the Tödi by the range of the Clariden Grat, north to the Hüfi Glacier. A less important branch encloses the Biferten Glacier, and terminates in the Selbsanft, south of Tierfehd. Towards the valley of the Vorderrhein a high promontory stretches nearly due south from the central peaks of the Tödi, and is crowned by the summit of the Piz Posta Biala. Another considerable ramification of the same mass terminates farther to the east in the peak of the Cavistrau.
