1887 - The wood fish tug, A. Booth was on her way to Duluth in tow after being sunk about a year earlier on August 27th, 1886 in a storm 20 miles southwest of Grand Marais, Minnesota.

1888 - An F2 tornado with a damage path 100 yards wide, touched down in downtown Marquette in the midafternoon and moved northeast. This tornado unroofed an entire business block. It was colorfully described as "a huge bird, with long fan-like wings revolving in a circular movement around a funnel-shaped body."
1926 - The wood, passenger and package freight Saronic had big waves overturn her coal-fired galley stove, catching her ablaze. She was run ashore on Cockburn Island in the North Channel of Lake Huron to save the vessel and crew, but still burned to the waterline. The hull was later recovered and rebuilt to the barge W.L. Kennedy. An engraving of her appeared on the face of the 1907-08 Canadian dollar bill. Her crew called her "Betsy."
