To piggyback this statement:RyGuy wrote:
An ice axe is a very important piece of equipment, hence my mentioning it being a lifesaving tool. However it's critical to know how to use it, before actually trying to use it. You're way more likely to injure yourself trying to play with it if you don't know how to use it, than actually being able to protect yourself with it. (Same could easily be said for Crampons)
If you are JUST getting into hiking in snow, and are on beginner routes mentioned, it's not essential, assuming you are staying on the route. That said, if someone wants to really get into winter hiking, spending the time learning how to use it and practicing on a low risk area like Saint Mary's is absolutely critical.
Hopefully that helps clarify a bit.

Don't glissade without an ice axe and knowing how to properly utilize it for self-arrest. I've seen people almost crack their heads open on Quandary because they were glissading and attempted to brake with poles. (The poles did not work and the folks missed rocks sticking out of the snow by mere inches.)
Watching YouTube videos on how to self-arrest isn't good enough. It takes practice to get that motion into your muscles.
