The following fossils were noted: Hapsiphyllum calcareforme ?, Pro- 
ductus cora, and Spirifer cameratus. 
(32) Rock as in 31 47 feet 
Eighteen feet from the top is a 3-inch band containing many specimens 
of Lithostrotion whitneyi. 
(33) Rock as in 31 36 feet 
These beds are characterized by an abundance of Lithostrotion penn - 
sylvanicum heads, especially the upper beds. The chert nodules extend 
through the upper 31 feet. 
(34) Dark grey limestone, medium grained 16 feet 
The basal bed rapidly erodes by shaling across the bedding plane. Just above this are 
many specimens of Lithostrotion sp. 
(35) Coarse-grained, dark grey limestone 92 feet 
A few fossils are scattered through these beds. 
(36) Mostly covered. Where exposed the rock is similar to that of 35 207 feet 
Rocky Mountain Quartzite (Permian) 
(37) Light grey quartzite, weathering reddish. Dip about 60 degrees west. 88 feet 
This extends down to the present flood-plain of Cascade river. The 
beds are down-faulted Rocky Mountain quartzite; there is much evidence of 
minor faulting in the beds. The main fault probably is near the junction 
of localities 36 and 37. 
Section 2a 
Along Cascade river, beginning at the southern part of Stewart canyon. 
This section was noted southward along the river, to which, for much of 
the distance, the strike of the beds is parallel. 
Rundle Limestone (Upper Part) (Lower Pennsylvanian) 
(1) A solid bed of limestone. Strike north 55 degrees west; dip 57 degrees 
southwest 5 feet 
(2) Grey limestone 97 feet 
— (3) Medium-grained grey limestone. This forms a conspicuous ridge. The 
upper 2 feet are full of chert nodules 15 feet 
The upper part is very full of Spirifer rocky montanus. 
(4) Light grey, medium-grained limestone, capped by 1J feet of calcareous 
shale, weathering brownish, the latter closed basaliy by a chert band 6 feet 
(5) Grey limestone 13 feet 
(6) Calcareous sandstone; the minute sand grains make up slightly less 
than half the rock mass. Chert nodules are present 3 feet 
(7) Very compact, fine-grained calcareous shale, dark grey above, black below 21 feet 
(8) Not exposed 27 feet 
(9) Light grey limestone 9 feet 
— - (10) Dark grey limestone 5 feet 
Contains many specimens of Spirifer rockymontanus; as the fossils are white, 
the dark colour of the enclosing rock renders them very conspicuous. 
(11) Very black calcareous shale. The rock is conspicuously fissile across 
the bedding plane. Dip 20 degrees west — 2 feet 
(12) Light grey limestone, weathering slightly brownish. Dip about 25 
degrees west — 32 feet 
(13) Light grey limestone, weathering slightly brownish. Dip about 30 
degrees west. Localities 10, 11, 12, and 13, pass over a slight fold 35 feet 
— (14) Very black calcareous shale, conspicuously fissile across the bedding 
plane. Effervescence in cold hydrochloric acid leaves the rock mass very slightly 
reduced in volume but become an impalpable black mud. Dip 57 degrees west; 
strike north 50 degrees west 3 feet
