(LAKE TOWNSHIP) -- There's been another report of a shipwreck uncovered off of Michigan because of lower Great Lakes water levels. Ron Krzeminski last month spotted what he thought was rocks in Lake Huron about 15 feet off the shoreline of Huron County's Lake Township. When he got closer, he discovered it was the bow of a ship. The ship appears to be about 18 feet wide and 60 feet long. Its name wasn't certain. Earlier this week, the remains of a wooden steamer named Aurora were uncovered at Grand Haven near Lake Michigan. The Great Lakes are shrinking because of drought and rising temperatures. Coast Guard Petty Officer Peter Brown says he expects more to turn up.
