Everywhere is walking distance if you have the time.
An avalanche is a very real winter hazard, especially in steeper ravines. Everyone in your group should have a good knowledge of avalanche safety. Education and training are critical, so each member of your group should take an avalanche safety course.
Steep slopes with unstable deep snow hold the deadly risk of avalanche. If you hike in the mountains in winter, here is some avalanche information you need to know:
The Avalanche Danger Scale
The guidelines before describing avalanche probability should be used with your judgement, experience and local knowledge.
Avalanche Safety Basics
Remember that avalanche danger rating levels are only general guidelines. Most avalanche accidents are caused by slab avalanches which are triggered by the victim or a member of the victim's party. However, any avalanche may cause injury or death and even small slides may be dangerous.
Always practice safe route-finding skills and be aware of changing conditions. Learn how to use, and always carry, avalanche beacons, probles and shovels. You must be able to carry out a self-rescue in the event of a burial as time is critical. If you must go for help, it is generally considered too late. Learn to recognize avalanche terrain and understand snow stability evaluation techniques to help minimize your risk.
No matter what the current avalanche danger there are avalanche safe areas in the mountains. Seek out the information needed to locate these areas and make informed decisions.
