The upper layers of this stratum apparently turn again into variagated beds like those below. At least in places.
5 Limestone, generally bluish grey on fracture but weathering brown or fawn colour & forming when on the tops of mountains crags & peaks quite columnar in aspect. Say at least 300'. Occurs in all the hills along the pass at various levels for 8 or ten miles. When half way down a mountain or near the base does not generally become columnar or craggy but forms sloping ledges. It being separated by many stratification planes.
6 Amygdaloidal trap. No doubt contemporaneous, but variable in thickness. Where seen between Camp No. 1 & the watershed probably 50' thick at least. Dark coloured, & forming cliffs in the mountain sides.
7 Fawn-coloured flaggy beds overlying the last & apparently an upward continuation of the limestone series which has only been interrupted by the trap overflow. Thickness not great.
