George Inlet

George Inlet (also George Arm) is a bay in the U.S. state of Alaska. It is situated within the Alexander Archipelago at the southern shore of Revillagigedo Island. It was named by the U.S. National Geodetic Survey in 1880 after pilot W. E. George, who created the first sketch of Revillagigedo Channel and Tongass Narrows.^[1]

Geography[]

George Inlet is a deep indentation of the southwestern coast line of Revillagigedo Island. The bed rock is chiefly black phyllite and slates of the Ketchikan series. The boundary of the granite of the Coast Range is probably 2–3 miles (3.2–4.8 km) to the northeast of the upper end of the inlet. The argillite series is often graphitic, and usually closely folded. Some belts of limestone occur with the Ketchikan series near the upper end of the inlet. Greenstones were found not to be so prevalent a rock type as elsewhere in the Ketchikan series. Near the entrance the two shores of the inlet are formed by granite, which occurs in the phyllites as an intrusive stock. The ore deposits are of two classes—first, the gold-bearing veins, and second, the galena- and zinc-bearing veins. ABoth classes of veins cut the foliation of the country rock. Prospecting has occurred here.^[2]
