Compare this section with home on road to Carne, use Broke for Thistons. This one is more reliable than this sketch.
See the above section described two pages to left.
On Wednesday I again looked at these immense fallen masses of broken coarse sort of a crytomerite. Now see that this gneiss is a fault breccia, made of mostly of the Pierce' pink and yellowish grey hard silicous ls. One block over 5' long, another 4', and a third 3'x3'. Other blocks are of a coarse quartz ss, and of the small pottle cyl, all marked together in the brick-red sandy mud-stone. All along here to the S of the fault gneiss it are the Ordovician strata, ortho to the N are the left down Saloe sandstone. The great fault lies between them.
