-Festoon sand continued to south end of island
-then made a gradual transition into a 40 m section of x bed and trough unit
-going up the west side is quartz rich festoon sand with a higher pelite content and then back into crossbed and trough at this location
PETROLOGIC DATA
Rock Number: 1
-at south end is large oval outcrop of simple 2 mica, 2 feldspar, tourmaline pegmatite approximately 10 m across
-good example of birds foot muscovite
-continuing south up west side the units run parallel to the shore
-one 30 m unit of massive chaotic conglomerate crosses the back of the bay
-across the north end of the island is all cross bed and trough in tight folds with the layering running cross E-W
-the fault doesn't seem to reoccur and the festoon unit is same before the north end
-in general the festoon unit is quartz rich at base becoming more feldspathic and then semi-pelitic up section
