(3) In the Sinclair gorge 1 5^ miles east of the valley road near the old 
construction station in the wide part of the valley loose limestone 
blocks full of Plectambonites saxeus (Sardeson) encumber the north 
slope near the bottom of the gorge. These talus blocks are derived 
from a bed of grey, dolomitic, heavy-bedded limestone about 600 
feet thick, which contains: 
7802 Crinoid stems 
Bryozoa 
Plectambonites cf. saxeus (Sardeson) 
“These limestones overlie thin-bedded, shaly limestone with trilobite fragments, 
which is considered to represent the Mons.” 
7795 “About 500 feet of cherty dolomitic limestone follows the beds with 
Plectambonites, the uppermost beds of which furnish Halysites pulchellus 
n. sp. and a Syringoporoid coral. 
(4) The Stoddard Creek section 2 is exposed north from the lower end of 
Stoddart Creek gorge around the west base of the mountain to the 
big ravine about 2 miles. 
It includes more than 3,000 feet of the Mons formation at the base, con- 
sisting of thin-bedded, argillaceous, grey limestone and calcareous 
shale, with trilobite fragments. 
Following these beds are several hundred feet of the heavy-bedded dolo- 
mitic limestones of the Beaverfoot formation. A fault contact 
of these beds with the Mons leaves their exact thickness uncertain 
in this section.
