An archaeological project has returned to an artifact-rich state park in the southern Adirondacks on what was once the focal point of the warring British and French empires more than 250 years ago.

A team of students and volunteers is trying to determine if a low stone wall along the edge of Lake George Battlefield Park and another structure being unearthed nearby were built during the French and Indian War from 1754 to 1763.

A dig in the park last summer uncovered a trove of artifacts from the period when thousands of British and Colonial American troops were posted at Lake George while fighting raged along New York's northern frontier.

The annual summer archaeological field school is sponsored by the nearby State University of New York at Adirondack.
