The main chain of the Glarus Alps can be divided into six minor groups, separated from each other by passes, the lowest of which exceeds 7,500 ft. The westernmost of these is the Crispalt, a rugged range including many peaks of nearly equal height. The highest of these are the Piz Giuv (3,096 m) and Piz Nair. The name Crispalt is given to a southern, but secondary, peak of Piz Giuv, measuring 3,070 m. West of the main group is the Rienzenstock, while a northern outlyer culminates in the Bristen. East of the Crispalt, the Chrüzli Pass separates this from the rather higher mass of the Oberalpstock (3,328 m).
