Friday afternoon has a way of making every trailhead look equally plausible. The pack is open on the floor, the forecast is being refreshed, and a weekend that began as one idea has acquired two respectable alternatives.

Horns Pond is the one to move around: its shelters are closed for the weekend. Avalanche Pass remains the handsome middle choice, while Lincoln Woods is the approach to remember for another season. A good plan is not the one with the most miles; it is the one that survives contact with the notice board.

This is the September 19–20 desk card, with the access notes and wider regional weather gathered below. Pack for the trip you are taking, not the trip the first draft imagined.
