(30) A fine-grained limestone with black chert nodules. These rocks dis- 
play many fractures across the bedding 67 feet 
Fossils are very abundant in certain beds near the middle of the locality, but 
the prominent fracturing renders it almost impossible to remove them. 
(31) Limestone in alternating beds of medium to fine grained; the latter 
bear black chert nodules, the former are chert-free. This locality usually stands 
forth as a prominent elm due to the more rapid erosion of the uppermost 10 feet 
of locality 32 135 feet 
Fossils are rare. 
Banff Shale (Lower Mississippian) 
(32) An alternation of dark, medium-grained limestone and thin (1-inch to 
3-inch) bands of unevenly bedded, shaly limestone. The fossils cease immedi- 
ately below one of these 3-inch bands. These limestones are capped by 10 feet of 
rock which fractures very prominently across the bedding plane and thus forms a 
weak zone causing the strata of locality 31 to form a cliff above and likewise aiding 
the softer beds of locality 33 to cause the lower rocks of locality 32 to stand out 
as a pronounced cliff 50 feet 
About 30 feet of the top of the cliff section is very fossiliferous. 
(33) The upper 50 feet is a rather heavy-bedded, coarse to medium-grained, 
dark grey limestone. The rock is almost entirely composed of fragments of 
crinoids and brachiopod shells, and is underlain by a 2-foot bed quite prolific in 
Syringopora and Spirifer. This upper part is underlain by about 30 feet of more 
thinly bedded, medium-grained limestone which, except for the lowest feet, 
fractures conspicuously across the bedding into small angular pieces 80 feet 
Few fossils present. 
(34) A coarse to fine-grained limestone, subdivided from above downward 
as follows: 300 feet 
(a) Fine-grained, thin-bedded, and fracturing prominently across the bedding 7 feet 
(b) Very fossiliferous shaly limestone, full of small calcareous concretions. 
This forms a persistent cave zone 3 feet 
(c) Fine-grained, thin-bedded, dark grey limestone, slightly fossiliferous. . . 23 feet 
(d) Dark grey, medium to coarse grained, with few fossilB 105 feet 
(e) Fine-grained and thin-bedded. Chert rare except in the basal few feet 
where it is finely disseminated and where likewise occur almost all the fossils 
noted. Fossils are here rather abundant 162 feet 
(35) Fine-grained, very dark grey to black shaly limestone. It is very thin 
bedded (1 to 6 inches thick) and is full of small black chert concretions. The 
uppermost 70 feet forms a strong cliff, weathering brown. All the beds are fossil- 
iferous, some highly so. A comparatively long exposed ridge of the lower beds 
gives good opportunity for collecting fossils 215 feet 
(36) An alternation of thin (3 inches to 1 foot) beds of black, very fine- 
grained limestone (calcilutite) and a black, very fine-grained shale, with a little 
calcareous cement. The latter fractures conspicuously across the bedding. The 
limestones weather a light grey, the shales brown. In the middle of this locality 
is a conspicuous cliff 330 feet 
No fossils were noted. 
(37) A black shaly limestone. This fractures very strongly across the bed- 
ding; in this respect it is similar to the shale beds of locality 36, but with an 
apparently higher content of iron it weathers to a more pronounced brown. This 
forms the conspicuous brown band almost immediately above the 1,000-foot 
cliff of the Minnewanka limestone, so noticeable when viewed from a distance. 
The upper part has a few more resistant calcareous beds, but they are entirely 
absent from the lower half. There is a conspicuous 6-ineh bed weathering a 
deeper yellow 40 feet below the top 200 feet 
No fossils were noted.
