Chrüzlipass
The Chrüzlipass (, Swiss German for Small Cross (as a diminutive) Pass) is a historic high mountain pass of the Glarus Alps, located on the border between the Swiss cantons of Uri and Graubünden (GR). Its connects the Maderanertal (UR) and the Tujetsch (e.g. Sedrun) in Surselva (GR). It is one of the lowest passes between the two cantons and is traversed by a trail.
The pass is overlooked by the Witenalpstock and the Chrüzlistock.
Below the Chrüzlipass, or more precisely between it and the Chrüzlistock, runs the Gotthard Base Tunnel.
