Term: Trip-boom (logging)
1. A log placed across a stream to hold the logs in a drive until the crew was ready to start them down. 2. A boom strung a safe distance above a dam, falls or fast rapids that could be opened to let logs through when the stream was clear, or closed quickly in case a jam formed below it.
