Peshtigo fire
On October 8, 1871, a forest fire driven by strong winds totally consumed Peshtigo and a dozen other villages, killing between 1,200 and 2,500 people and engulfing approximately 1.5 million acres. This fire, known as the Peshtigo fire, was the deadliest in American history. Unidentifiable remains of hundreds of residents were buried in a mass grave at the Peshtigo Fire Cemetery. The Peshtigo Fire Museum features several items that survived the fire, plus other artifacts from the area's history. This fire happened on the same day as the Great Chicago fire, the Holland, Michigan fire, the Port Huron Fire of 1871, and the Great Michigan Fire in Manistee, Michigan.
