3 Nov. Bold bluff extending for a mile or more westward from Soap- stone Valley - 900-1000 feet high by es- timate of St Clair and myself - generally red gneiss with predominan- tly hornblende's bands near bottom. Trap dikes ca 200 ft wide de- sends diagonally across face from valley to point and then rises again more abruptly from sealevel, forming a broad V which lies upon its side - Many tent shaped grottos at sea level and above. a line of them 50-75 feet above the sea seems to indicate the locus of a former sea level (corresponding in height to the raised beaches at the head of the bay). Higher ones are to be seen, but especially along a steeply inclined (70°±) fault zone. Approaching the second point, two miles from the valley and four miles from the head of the bay, one sees par- ticularly beautiful banding in the gneiss, while near the point sigmoid flexures are pronounc- ed.
