I'm going to try to keep this organized, because I have a few separate questions.
I'm planning to hike the JMT this year in early July, and based on the snow reports it looks like there will definitely be snow/ice on the high passes (Mather, Glen, Forrester, etc.).
I'm considering buying an ice axe/crampons, but have the following questions:
1. without training, is the axe still useful for crossing icy traverses?
2. how long/expensive is the training for proper use?
3. once I took a class or learned from a qualified instructor, could I teach someone else to use the axe? The issue is that my traveling companion won't have time to take any training courses.
4. we have the flexibility to wait until 9 or 10 to cross the high passes, but will this be enough or are there north-facing portions that simply won't soften up?
5. how much better are MYOG pan-head screw crampons than just trail runners?
6. if I do buy an ice axe, is there a minimum length to make it useful?
7. if not, what's the lightest/cheapest ice axe that will still be reliable for traversing and self-arrest?
8. for summer snow travel, will lightweight trail runners and light wool sock be enough to keep my feet warm while hiking?
Thank you so much for your help!
