do not show the same number of Septarion nodules formerly seen in them in some horizons. The hardening appears to have taken place in a somewhat different way. There being somewhat continuous hard layers & then intercallated sandstones. Some places however still show large nodules. Found in some broad lenticular bands many fossils though not very well preserved. Still undoubtedly marine & Cretaceous. Inoceramus. Ostrea?[Dawson's ?] Avicula?[Dawsonís ?] Ammonites. & several Gastropods. (?[Dawson's ?] of stone containing these could be called a limestone)

The beds overlying these representatives of the sombre clays are sandstones which appear to be much more hardened than where seen further East & may be taken to stand for the highest division of the Cretaceous. They generally form a prominent ridge round the mountain & like the other beds dip away from it. These do not appear to contain fossils.
The formation traced from E of Milk R. & here is thus above Cretaceous & as supposed represents the lower beds of the Tertiary. The transition between the Cret. & Tertiary becoming more complete westward. The passage from Salt to Fresh water conditions going on very gradually as the many oyster beds show.

The sandstone zone of Milk R. valley may not unprobably represent the Roche Percee Sandstone.
