the south, which they appear to rest upon. Locally, however, the 

 attitude of the beds is so variable that it is quite possible for 

 particular miuor sections to occupy their normal relations. 



§ 13. The general locality was visited by Charles D. Walcott and 

 the writer in 1909, when we secured specimens of the Oholus listed 

 in § 14. In a second visit to the locality the writer spent some time 

 iu collectLng from the graptolite horizons exposed in the stream bed 

 just west of the station (probably the one referred to by McConnell) 

 and in the railway cut between that stream and the station, and in 

 measuring and collecting from the section of 06o^ws-bearing shales 

 and limestones exposed in the bed of a stream which is spanned 

 by a masonry bridge a few himdred yards east of the station at 

 Glenogle. We shall use the term Glenogle Creek for this stream. 



The beds outcropping in Glenogle Creek strike north-west-south- 

 east, and dip almost vertically (thus differing by 60 to 70 degrees 

 from the dip of the massive beds which overlie them), and they 

 occur stratigraphically below an exposure of the graptolite-bearing 

 shale in the small cutting just east of the masonry bridge. 



The Glenogle Creek section is exposed in the bed of the creek, and 

 outcrops on the east side of the creek between the masonry bridge 

 and the mouth of the canyon. It may be described as follows :— 



§ 14. Glenogle Creek Section. 

 Top (East) :— 



1. Covered by railroad grade, in which there is a cutting 



exposing graptolite shales, and the Kicking Horse 

 River. 



2. Fairly massive light-blue limestone, slightly mottled and 



weathering to a dirty grey ..... 2 it. 



3. Thick-bedded dark-blue limestone, considerably sheared, 



with some layers of blue shale . . . . . 3 ft. 



4. Blue limestone in bands 1-3 inches thick with intercalated 



blue shale bands an inch or more m thickness . . 4 ft. 



5. Massive band of dark-blue limestone .... 16 in. 

 Fossils in upper 4 inches which weathers slightly yellowish. 



Locality No. 1. 



6. Blue shale 3 in 



7. Blue limestone ........ 6 in. 



Fossils in upper 4 inches which weathers slightly yellowish. 



Locality No. 5 {Obolus, etc.) 

 S. Thin-bedded blue limestone and shale similar to 4 . . 12 ft. 



Fossils 8 feet above base, Locality No. 2. 



Fossils 6 feet above base, Localitj' No. 3. 

 9. Fairly massive-bedded blue limestone . . . . 1 ft. 



Fossils in upjier 4 inches. Locality No. 4. 



10. Cleaved shales ........ 1 ft. 



11. Covered + 25 ft. 



12. Grej', blue, and black shales, sheared, exposed in gorge 



above the bridge. 



This section should be compared with that portion of the section 

 measured in the summit of the Beaverfoot Range (§ -5), which under- 

 lies the graptolites of bed No. 19.
