July 27. Bonne Bay. Dembars mts
Dembar's mts are as follows:
He cruised along the northeast side of the East Arm into Deer Brook Bay. At about the saw mill on Charles Creek Brook, the strike of the L.C. trends around so that in general the beds dip off to the southwest and finally south, and in Deer Brook Bay a little north of west. As a result we rise in the section going toward Deer Brook. In detail the the dip varies frequently as much as 30 or 40 degrees but in general it is as stated. There seems to be a broad and steeply plunging anticlinal structure at about the saw mill where we find the coarse exposed layers of the L.C. farther over rise through the L.C. in going along shore either way.
It can't seem that the opposite shore of the Arm is formed of Bredmant and dolomite, the strike of these beds also tending in general conformity with both of the Cambrian and with the other line.
On Deer Brook Arm we begin in the lower part of the Bredmantion. Buff to light gray dolomitic li. like those seen near the "Scarels" at Polson Pits. Here the dip is 35° S. 65° W. The section rises slowly toward Reddys Harbour. The upper Bredmantion becomes darker gray in color and weather rough with irregular stringers of quartz standing up in relief on the surface. [See Q. for the Oil company]. The section continues across the next little curve with patches 200 foot of slate and dol. and the dip gradually steepens up to vertical. We then pass into 30 feet of dark slate colored beds that weather to chifts, and then heavier reddish clay gray moy. li. again with small Brachinites in abundance, Lefendition, etc. These beds take on the character of the Chazy and show an abundance of gastropods. About 100 feet from the Chazy beds form the point next to Reddys Harbour. Dip 85° N. 70° W.
