Even after the logs arrived at a river, the remaining leg of the journey downstream to a mill was often challenging. It was common to have logjams—accumulations of logs that prevented logs from floating along the river—that could stretch as far as 15 kilometers, and this problem was exacerbated as increased pressure was placed on the northern Midwest pinelands. Log and chain barriers called booms had to be constructed to help keep the logs moving steadily and control their direction.
