South Point

Yesterday we visited the southern most point of the United States, appropriately named South Point. We hiked about 3 miles down the coast to a green sand beach that is made primarily of olivine. At the beach, we split up into 3 groups and did a stratigraphic column of the cliff adjacent to the beach.
