Why is walking downhill in mist harder than going uphill?

Going uphill funnels you toward a single point (the summit), but descending spreads you out in multiple directions—mountains go down into several valleys that all look similar in poor visibility. A small position error at the top can send you down the wrong spur entirely, into a valley you never intended to visit.

How often should I check my compass when descending in mist?

Check it more frequently than feels necessary—it should be constant guidance, not occasional reassurance. Check before committing to a spur, when choosing between similar-looking descents, and any time something feels wrong even if you can't say why.

What should I do before leaving the summit in mist?

Get your navigation sorted while you're still somewhere identifiable: take a bearing for your descent, identify what the first confirming feature should be and roughly how far away, and work out expected timing. Don't just point yourself downward and hope for the best.

Navigating Downhill in Mist: Why Descending in Poor Visibility Is Harder Than Climbing

Descending hills in mist is considerably harder than going up because instead of funnelling toward a single point you're now spreading out from one, gravity encourages commitment before certainty, and being thirty metres off your intended line at the summit can mean you're heading down the wrong spur entirely into a valley you've never heard of.
