Rocks dip 5o to 10o N.W. and trike N45o to 60oE. They probably underlie the strata on the N.W. side of the bay at Sta. 64AHr1. At the north end of the exposure the rock is cheifly light- to dark greenish-gray siltstone with some interbedded sandstone. Farther south the section includes a greater proportion of sandstone, much of which is calcareous. Thin beds of carbonaceous shale were noted at two places.
