Fear: what it is doing, and what to do with it

When the GPS dies: navigating with what is left

A dead phone in poor visibility turns a routine day into a genuine problem. The backup is a map, a compass and a set of habits that most people no longer have.

Debriefing a near miss, without turning it into a trial

The most valuable safety information available to any group is the thing that nearly went wrong last month. Most groups never discuss it, because the conversation is uncomfortable.

Cutting weight: what actually matters and what is theatre

Weight reduction has a clear hierarchy and most people work at the wrong end of it, sawing handles off toothbrushes while carrying a pack that is a kilogram heavier than it needs to be.

Headlamps and the night you did not plan for

Almost nobody sets out intending to be in the dark. A significant fraction of mountain incidents involve people who are, and who did not bring a light.

Multi-pitch efficiency: speed is a safety system

On a long route, the thing most likely to hurt you is not the climbing. It is being on the wall at six in the evening when you expected to be down by two.

Rappel accidents: the most avoidable deaths in climbing

Rappelling is entirely under your control, takes place on a system you built yourself, and kills experienced climbers with grim regularity. The failure modes are few and every one of them is preventable.

What a helmet is actually rated for, and what it is not
