ZARZYNSKI TO SPEAK ON LAKE GEORGE RATEAU SHIPWRECK Underwater archaeologist Joseph W. Zarzynski will show the award winning 57 minute long documentary-"The Lost Radeau: North America's Oldest Intact Warship" on Thursday, May 17, at the Saratoga National Historical Park Visitors Center., at 7:30 pm. Speaking at a joint meeting of the Stillwater Historical Society and the Old Saratoga Historical Association, Zarzynski will share the history, sinking, discovery, and archaeological study of the 1758 "Land Tortoise" radeau shipwreck in Lake George. The "Land Tortoise," a seven-sided floating gun battery, was intentionally sunk in October of 1758 by the British to keep it safe from the French over the winter. However it slipped into deep water and couldn't be located the following spring and was considered lost. Zarzynski rediscovered it in 1990. This program, open to the public free of charge, is one of several in this region held to commemorate the 250th anniversary of the French and Indian War. For more information call 583-0506.
