cannot get tell. It maybe the one below the Cow Head conglomerate
or one in the Parrot Pond series.
I hope to clear up the matter during the day. Later the fore conclusion is that it is the sandstone below the
Cow Head conglomerate of my two sides, across 1/2 mile and goes over 100
for ashore again just north of the mouth of Portland Creek.
Here is a good man of Cow Head conglomerate the east facing face being
vertical and nearly N-S. It probably is a fault face but there is no clear
evidence to prove this. It does not seem to have any direct relation to the
