The First Grade Pod is named after Lake Huron, the fifth largest lake in the world. It was the first of the Great Lakes to be discovered by European explorers. In 1615, Samuel de Champlain followed the route of the Ottawa River to come upon this beautiful "Freshwater Sea". Many shipwrecks are scattered beneath the surface of this body of water with five bottomland preserves in Michigan. Lake Huron's shoreline consists of dense forests, beautiful scenery, and an abundance of rich natural resources. Much of its shores remain as wild as they were when the Huron Indians were the only travelers along these waters. Lake Huron has the longest shoreline counting the shores of its 30,000 islands.
