  • Snowmaking hoses – Danger, high pressure! Do not ski over hoses!
  • Snowmaking hydrants – Do not fall in open sites!
  • Snowmobiles – Make yourself highly visible to avoid collisions!
  • Grooming Operations – Give groomers a wide berth and make yourself visible to operators, do not assume they see you!
  • Winch Cat grooming operations – Dangerous cable! Under no circumstances may anyone access any area within the Resort where winch cat operations are taking place. Such work will involve cables stretched tightly across the terrain and is very dangerous. Skiing into them could result in serious injury or death. Respect strobe lights and signage.
