Plot bearings at home, transfer checkpoints to a route card, and keep your thumb on the map as you move. Count paces for short legs, use contours for handrails, and confirm aspect with a simple compass. Barometric hints help, but judgment rules. Rehearse these habits before committing gullies.
A tiny headlamp with lithium batteries rides in an accessible pocket, never buried. Move by starlight only when terrain is friendly and partners are alert. Mark turnaround times, and honor them. In winter, pre-rig a reflective tag on the pack to locate each other fast during windy transitions.
Carry a compact first-aid and repair pouch: tape, gauze, blister pads, needle, floss, zip ties, and ten meters of cord. Add a whistle, mirror, and paper notes with contacts and route plans. Share your itinerary, establish check-in windows, and practice retreat drills together before the mountains test you.
