Learn to read the mountain.

Heavy, wet snow doesn't fall evenly across a mountain — it depends on where the sun has been. Here's how to check aspect before you commit to a run.

From above, a convex roll can hide exactly where the terrain breaks away. The cliff layer marks that break before you're already over it.

A danger rating on its own doesn't tell you which slope it applies to. Placing the bulletin on the terrain in front of you does.

An open, fresh-snow slope can look perfect and still sit squarely in the angle range where most slab avalanches start.

Not all powder stays powder. Aspect and sun decide which slopes hold their snow longest — well before you get there.

Fresh snow doesn't stay where it falls. Wind loads some slopes and scours others — often within a few hundred meters of each other.

The forecast said fresh snow. Down at the base it's wet and disappointing — a few hundred meters up, it might be exactly what you were hoping for.

The same slope can be bulletproof at 9am, perfect corn at noon, and slush by 2pm. Spring snow is a window, not just a place.

Shade preserves snow — sometimes that snow is powder, sometimes it's ice that never got the chance to soften.

Flat light erases contrast before it erases the terrain. Ridges, gullies, and rolls are still there — you just can't see them the way you normally would.

A few hundred meters of elevation can be the difference between a rained-on base and dry snow that's still holding up.

Snow quality isn't random. Aspect, elevation, sun, and temperature decide it — and they change through the day.

Terrain, runs and avalanche layers only help if they're already on your phone before you leave coverage.

Mountain safety info and avalanche risk on your Lock Screen and Dynamic Island — information, not a safety net.
