A log boom was 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.
