Chaser – Person that unhooks logs on the landing.
Chokersetter – Person that wraps chokers (cables) around logs for machine (yarder) to pull to landing.

Conk – A fungus that grows on wood and is indicative of rot or disease in the tree.

Rigging Crew – Loggers that set up and maintain cable yarding systems.
Rotation – the period of years needed to reproduce and grow to maturity a specific crop of trees. In Washington on the west side of the mountains, the rotations can begin as low as 40 years of age and go to over a 100 years for fine sawtimber. The eastside rotations generally start at about 80 years because of slower growth with drier conditions.
Road Change – Moving to an area adjacent to that which has been cleared of logs in tower logging; done by changing the tailhold.
Slash – debris left after a logging operation.

Stumpage – the price paid to the owner for a tree or trees as they stand on the stump.
Strawline – Small, light cable used for rigging tower lines.
Sustainable Yield – the practice of harvesting each year the equivalent of what you are growing. Therefore, you could log forever – say on a 100 year rotation on 100 acres – one acre each year forever.
Tailhold - A sturdy stump or tree used to support tower guy lines or yarding lines.
Turn – A load of logs which is dragged to a landing by a tower (yarder) or tractor.
