The whole mass of strata dipping W. or W.N.W. towards the axis of the chain, broken off abruptly to the E. The rocks chiefly composing the Eastern slopes belong to the Great Limestone Series (5) & the slaty & sandstone beds underlying it (4.3.2.1.). Where gaps on the Eastern wall allow the inner Mts to be seen the Trap & fawn beds & the upper Red Series are extensively developed forming summits of Mts. These appear to be nearly flat or have very gentle Dips. The general structure of the range about here would therefore appear to be well represented by the Section drawn out for the Kootanie pass & to be very regular. The red band No. 4 persists Northward as far as the structure of the Mts could be seen. Generally cropping out from 1/3 to 1/2 way up the Eastern slope. The trap horizon (No. 6) also appears to be very constant. It is seen in many of the hills & fragments referable to it are found in great abundance everywhere round the foot of the Mts.

The rocks of the Mts do not end abruptly where they appear to do & where the vegetation of the foothills slopes up to & covers the base of the Mts. In sections sway? by streams they can be seen at some distance from the Mnt slopes.

Softer sandstones & belonging to the Cretaceous series probably occur in some places quite close to the Mts bases. Did not however see any fossils in them by which their age might be recognised.
