Background and detail
Background. The St. Croix River, a roughly 169-mile (272 km) tributary of the Mississippi flowing through Wisconsin and Minnesota, is free-flowing except for the hydroelectric Saint Croix Falls Dam. In 1886 the river was blocked by a log jam so large it was described as the "jammedest jam," and its removal demanded steamboats and dynamite.
Clearing Efforts. The 1886 log jam was exceptionally large, earning the description 'jammedest jam.' Standard methods were insufficient, so workers employed steamboats and dynamite to break up the mass of timber. This event underscores the scale of logging operations on the river during this period.
