This site shows a picture of a high lead system, which is best used in clearcuts because of the way it is moved to different settings, and also because it usually just has butt rigging and no carriage on it. That makes lateral yarding (pulling the log across to the corridor) very hard to do.

And here is a skyline, which is better suited for partial cuts because the carriage can carry the mainline down to where it can be pulled through and hooked to logs that are a ways away from the corridor.

Skyline is often confused with high lead.
