fossiliferous Castle Mountain limestone of McConnell’s Castle 
Mountain—Bow River series on the Canadian Pacific Railway. 
Daly bases his correlation of the other formations on their 
position with respect to the Siyeh and their lithologic resemblance 
to certain members of McConnell’s sections. Willis placed all of 
the Lewis series in the Beltian since the Beltina danai beds of the 
Altyn formation are conformable with the overlying beds of the 
series, whereas in the Belt range the Cambrian unconformably 
overlies the Beltian and is separated from the Beltina danai bearing 
beds by 7,700 feet of sediments. Walcott also found a plane of 
unconformity at the base of the Fairview sandstone, the lowest 
Cambrian in the Bow River section. 
Daly' describes the rocks along the Canadian Pacific Railway, 
between Golden and Kamloops, British Columbia. 
Pre-Cambrian rocks dominate in this section. He. classifies 
them into the Beltian and pre-Beltian or Shuswap. The two are 
separated by an unconformity. His divisions of the Shuswap or 
pre-Beltian follows:

The existence of the individual members of this series is certain, 
but their relative thickness is still in doubt with the exception of 
the Tshinakin limestone and the Sicamous limestone.
