We left Tenant's Harbor after a lazy morning and breakfast and cruised several miles north to a group of small islands at the north end of the Muscle Ridge Channel. We anchored between Dix, High and Birch Islands. High and Dix Islands were granite quarrying sites in the late nineteenth and early twentieth centuries. In the attached picture gallery is a picture of one of the two granite wharves on High Island that were used to load massive pieces of granite onto ships before the days of heavy machinery. Granite was shipped from here to, among other things, build post offices in New York, Philadelphia and Charleston. At its peak there were more than 2000 quarymen and 150 buildings on Dix Island. Today it is owned by a private association with a few houses, no electricity and hand pumped water. We did walk around the island, heeding the sign shown in the picture and saw some great views of the surrounding islands. I'm adding more pictures to the attached gallery of our latest travels. At the end of the day we headed back to Camden, arriving as the sun set over the Camden Hills. We chose not to stay out another night as thick fog was (correctly) predicted for the next morning.
