Travel and Terrain Advice
Weekend sunny weather is something that many people go out into the backcountry. Be vigilant of those who are above you by being mindful of your surroundings and imagining what decisions other groups will make. Glide cracks form extensively at low elevations. Continue the action of making the right terrain selection. Clear skies over the weekend will result in another busy day in the backcountry. Take into account other people's decision-making around you and watch for people dropping in above you. Continue to make good terrain choices at all elevations as glide cracks are widespread at lower elvations.
