Further Note on the Earthquake in Southeastern Alaska. The tidal wave that washed huge trees off the sides of mountains above Lituya Bay was certainly one of the biggest in history. A triangular area about a mile across its base and reaching an altitude of 1800 feet at its apex, on the northern shore of the bay close to its T-shaped head, was washed bare to bedrock. Farther out towards the ocean, the wave still rose to heights of about 200 to 300 feet and carried its destruction to nearly a mile from the shore in some places. Although two fishing boats were sunk with the loss of two lives, a third was carried unharmed from its anchorage within and washed right across La Chaussée Spit, which closes the bay off from the ocean. The skipper, Howard Ulrich, estimates that he and his small son cleared the spit at an altitude of 100 feet or more. Near Yakutat, some 80 miles north, three more people lost their lives when a large part of the southern end of Khantaak Island heaved twenty feet into the air and then disappeared beneath the waters.
