We started our day in Shark Cove, on the western side of the island. There are some fantastic metaconglomerates there. Natalie is going to work on them for her senior thesis, so we spent the morning sampling metaconglomerates. It was a very productive morning - we got about 12 cobbles in all.

After lunch along the beach we drove up to the end of the airport runway. Along the road there are fantastic looking blocks in melange matrix. It's a super place to see the block matrix relationships. We even saw several blocks with rinds. The problem is sampling them.... The rocks are extremely weathered and it's simply impossible to get anything fresh from them. We spent a little time trying. We ended up getting some metaultramafic rocks and reaction zones adjacent to them. We ended our day by going to the super large mafic block - Gorgon - and collecting some pretty garnet amphibolites to take home with us.
