DepthsLimitations.That part of the sound that has been surveyed, between Murray Island and Harrison Island, indicates depths in mid channel of 21.9 to 40.2m. Deep water lies off the steep E sides of the islands; off the mainland shore the water is shoal up to a distance of 0.5 mile. Moore Island (58°33'N., 78°34'W.), the N island in the Hopewell Islands, lies close SE of McCormack Island. It has an elevation of over 31m in its central part. An islet, 1.2m high, existence doubtful, was reported in 1978 to lie 2 miles WSW of the S end of Moore Island.
