Page "Glarus Alps" Paragraph 8

The eastern limit of the latter group is marked by the Segnas Pass — the most frequented of those connecting the Canton Glarus with the Vorderrhein — beyond which arises a wide-stretching mass of rock and glacier, which is part of the Glarus thrust and culminates at Piz Sardona.

This mass is cleft by a deep valley — the Calfeisental: one branch, culminating in the Pizol ( 2, 844 m ), extends east over Pfäfers, while another, including the highest peak of the canton of St. Gallen, the Ringelspitz ( 3, 247 m ), runs due east to the low Kunkels Pass ( 1, 357 m ), separating this range from the Calanda.
