Section 1, localities 1 to 19 inclusive, was made along the road and 
Cascade river from northeast of Bankhead to the junction of the river with 
Devils creek, the outlet of lake Minnewanka. Here was an excellent 
section of the Spray River shale and the Rocky Mountain quartzite. The 
remainder of the section (in the Rundle limestone) is continued upon the 
western side of the river about 1J miles north of its junction with Devils 
creek 1 * * and was measured, across the strike, eastward to Cascade river. 
The two parts of this section were connected by a common datum plane 
(the beds of locality 17) so that the measurements could be made rather 
exactly. 
Section 2a extended south along the east bank of Cascade river from 
Stewart canyon to the beginning of section 2. It included some very black 
shale beds which were largely concealed in section 1. 
Section 2 began at Cascade river just south of its junction with the 
most southerly gulch north of Minnewanka lake entering the river from 
the east. It was continued east-northeast along the northern shore of 
lake Minnewanka, that is, along the southwestern edge of the Palliser 
range, including the southern edges of mount Astley* (location A on Figure 
1), the Castle,® and mount Standly. 4 * This section gave excellent exposures 
of the Rundle limestone, the Banff shale, the upper part of the Minnewanka 
limestone, and much of the lower part as well. 
Section 3 was made rather hurriedly up the southern slope of mount 
Aylmer, at the western edge of the head of Aylmer canyon. Its purpose 
was to secure the contact between the Spray River shale and the Rocky 
Mountain quartzite. 
Section 3a was made somewhat farther down the slope of mount 
Aylmer to include some very fossiliferous beds. 
Section 4 was made along the northern edge of the valley forming 
the eastward continuation of the Lake Minnewanka valley. The 
section extends from the northwestern end of West lake to the gully 
at the western end of Middle lake. 6 The purpose of this section was 
mainly to get the lower part of the Minnewanka limestone and its 
relation to the Castle Mountain group below. 
Section 1 
Along road and Cascade river from northeast of Bankhead to junction 
of river with lake Minnewanka, and miles north, along a line north 
58 degrees east. The strike of the beds is about north 22 degrees west, 
dip usually about 40 degrees southwest. 
1 This creek has been practically obliterated since these sections were made, by the damming up of the lake 
for waterpower and the consequent raising of its surface 9 feet above its former height. 
* The name applied locally to the peak between Stewart canyon and the western end of lake Minnewanka. It 
was given in honour of Mr. C. D. Astley who lived at its southern foot for twenty years. 
* The local name of a castle-like cliff, as seen from the lake, east of mount Astley, formed of almost horizontal 
Btrata and separated from the rocks east and west by ravines. 
* A name here applied to the prominent projection just west of Aylmer pass, between the pass and the lake. 
The name is ijiven in honour of Mr. John Standly who was the first to operate profitably on this lake a boat for the 
accommodation of tourists and thus assured the continuation of this accommodation. 
* There are three lakes in this valley between lake Minnewanka and Devils gap, which are named West, Middle, 
and East lakes, respectively.
