Planning ahead? From Sat, Oct 10, 8:00 PM, it gets worse

Ice or hard snow likely above about 10,000 ft. On the section "Baldy Bowl, above the ski hut", that means crampons, ice axe and helmet, and the training to use them. Without them, turn around below 8,200 ft.

From hikers on the mountain

Soon you'll be able to tell us what you saw, by voice or photo, and a fresh report will beat our estimate for that spot.

Until then, the newest posts in the links on the left are the best ground truth. Check the date on every one: anything from before the last storm is out of date.

If the page says crampons, ice axe and helmet

CramponsNot microspikes: rescuers say most recent deaths involved microspikes on steep ice. Fit them to your boots at home.

Ice axeAnd the skill to self-arrest. Practise on a safe slope with a course before you need it.

HelmetA climbing helmet. Falls here end on rocks.

Satellite messengerMuch of the mountain has no cell signal.

A turn-around timeDecide it before you start, and keep it.

What this estimate can't see

This is a model, not an observation. A 1 °C error moves the snow line about 500 ft.
It cannot see one shaded chute or a boot-packed icy track. Treat any shade as icier than shown.
After the first storms of the season, thin ice on rock is common and hard to see. We lean on the side of more gear.
