Beds immediately below limestone not well seen, but probably all variagated sandstones &c. The crimson beds, or lower red Series then come in say about 200'.
(These red beds were not distinctly observed in Mt Yarrel section).
Below the red beds & forming the point of the hill near camp No. 1. which seperates the S.Western & Western branches of the pass. Variagated sandstones & quartzites.
A gentle anticlinal runs nearly W. (Mag.) into the nose of the mountain mentioned, & follows the ridge seperating the two brooks. In the S.W. Brook a lower greenstone trap is exposed. Very hard but so traversed by joints & slikensided surfaces that hardly possible to obtain a clean faced specimen.
