THOMPSON'S COAST PILOT, 23. High Island. The best anchorage is under.the east point of the island, in 5 to 7 fathoms, sandy clay. When laying here, should the wind chop round to the NW, you can run out, round the east end of the island, giving the point a good berth, and follow the island close round and come out to the westward, leaving Gull Island to port or to starboard pretty close to. The course from the south side of Gull Island to Rock Island Lighthouse is WSW, but if the wind should be southerly you will have to haul up a point higher, as a southerly wind always sets a stiff current through the passage and along the islands leading into Green Bay.
