Travel and Terrain Advice
Conditions call for careful terrain and route selection. Start using small terrain and gentle angle slopes. Above the Treeline, watch for wind slabs formed by snow carried by westerly winds, and consider changes in slope orientation and terrain wind direction. Below Treeline, expect to be limited in your activities due to bushes and shrubs that have not yet filled in, and gullies. In previous years, the last part of a possible tour route may be very time-consuming. With that in mind, choose your route carefully. Continue to have a good holiday.
