112 m. Between this point and Laggan one has the 



179-2 km. best view of the valley of Ten Peaks, also 

 Paradise valley and the majestic peaks of 

 the Bow range. The peaks which stand 

 out in prominence are a few of the Ten Peaks, 

 including Mt. Fay and Mt. Deltaform (11,225 

 ft. — 3,421 m.); also Mt. Temple (11,626 ft. — 

 3, 544 m.), the highest peak in the range 

 visible from the railway. On approaching 

 Laggan, Fairview, Aberdeen, Whyte, and Vic- 

 toria become visible. 

 113-9 m. The first and lowest exposure of Pre-Cambrian 

 182-2 km. occurs to the right of the railway. It is a 

 coarse pebbly sandstone containing pink felspar. 



115 m. Laggan— Alt. 5,037 _ ft. (1,535 m.). From 



184 km. this point, type localities for Cambrian and 

 Pre-Cambrian formations will be visited. A 

 driveway and a railway lead up to Lake 

 Louise and the Chalet. This lake is situated 

 over 600 feet (183 m.) above Bow river, 

 at the front of a large cirque which is occupied 

 at the south end by Victoria and Lefroy glaciers. 

 The lake is surrounded by Lower Cambrian 

 quartzites of which the St. Piran formation 

 stands out in prominence and forms precipitous 

 cliffs. The contact between the Lower Cam- 

 brian quartzites and the Middle Cambrian 

 limestones is well shown in the lofty mountains 

 about this valley. The illustration on page 

 178 shows the Mitre with Mt. Lefroy on 

 the right, Mt. Aberdeen on the left, and a 

 portion of the Lefroy glacier with a well 

 defined bergschrund. The cliffs are Lower 

 Cambrian, and the Mitre is capped with the 

 Cathedral limestone of the Middle Cambrian. 

 The pass to the right is called the Death Trap 

 on account of its dangerous position. 



A visit will be made to Valley of the Ten 

 Peaks, and the mouth of Paradise valley 

 will be passed on the way. Both are typically 

 hanging glacial valleys with glaciers at their 

 upper termini. In the former the valley is
