The international boundary between the United States and Canada divides the waters of the Saint Lawrence River on this 2011 survey, marking the northern reaches of Jefferson County. Small clusters of homes and family farms are anchored by settlements like Saint Lawrence and Warren, where local history is preserved at the Saint Lawrence Cemetery and Sand Bay Cemetery. The shoreline is deeply indented by numerous coves, including Millen Bay and Sawmill Bay, which served as critical access points for the river-based economy of the Thousand Islands region.
