Welcome back to the Mountain Conditions Summaries. It feels almost like summer today but it has been a long cool spring and in the Valleys and the Mountains it really feels more like early May than late May.

Skiing is still possible and even reasonable at times on the Icefields and in most Alpine features. Snow and ice climbing conditions are also potentially good. The caveat being that as always in the spring you need a cold, clear night to get the kind of freeze you can trust.

Regional Summary: Rockies and Columbia Mountains - October 21, 2021

Much of October seems to have come as a consolation prize for enduring several weeks of smoke this summer. It looks like this will be coming to an end over the next few days.

The unseasonably warm temperatures continue on Friday, with freezing levels rising as high as 3000m. The western edge of the Columbia Mountains will see precipitation starting midday Friday and lasting through the weekend.
