Talle Head section.
10' Alternating lewy layers about one foot thick separated by intervals of thinner bedded dolomite.
This brings us to a smaller core where there is a large fault. The fault strata tilted strikes across the core, being exposed on both sides of it, and there is a newly continuous exposure of a slightly lower level around the face of the core.
165' The small joint south of the horn is near the middle of a core, subdividing it into two smaller cores. The southern of these about 1/4 mile across the lower found interval of Richardson. Here the cliff needs a distance of 50 to 100 yards from the shore and is largely covered by talus but several exposed outcrops serve to show the character of the white sequence, and they are also more or less exposed as rocky ledges at low tide.
These beds are even bedded Hurst-ley maj. li., in layers 2 to 6 inches thick, and many of these have a fine rift-like bedding like the schneiders and a little of some sedimentary lines. These li., do not over them or simple as those below and appear very fine-grained and earthy, weathering very lightly.
About 20 feet from there I find Didymograptus and heden of are seen silicium pseudonipples of a light red part.
There are recanimal gneiss. 1 to 3 feet thick that are very thin-bedded weathering into them chips almost like shale. Richardson's estimate of 160 feet for his I division appears to be about correct.
End of Reedman Turn. Seen 280 feet.
