Log boom

Timber marks on a log building in Sweden where they are called flottningsmärke

A log boom is a barrier placed in a river, designed to collect and or contain floating logs timbered from nearby forests sometimes called a fence or bag. The term is also used as a place where logs were collected into booms, as at the mouth of a river. With several firms driving on the same stream, it was necessary to direct the logs to their owner's respective booms, with each log identified by its own patented Timber Mark. One of the most well known logbooms was in Williamsport, Pennsylvania, along the Susquehanna River. The development and completion of that specific log boom in 1851 made Williamsport the "Lumber Capital of the World".
