Hi all, I'm wondering what the best way to go about learning basic snow travel skills is without spending tons money. I am thru-hiking the Pacific Crest Trail this spring and, although it's too early to tell, the initial snow reports in the Sierras suggest that this year my have a pretty high snow pack. I want to feel really comfortable with using an ice axe, self-arresting, etc, before I get out on the trail, but I'm not sure the best way to go about learning and practicing these skills. Any suggestions on where to start? Thanks!
