So yesterday I don't know if anyone here was at Alta but there was fog up near the top so it was skiing in very flat light. I had a problem throughout the day with moisture condensing on my goggles then freezing and I couldn't see along with the flat light. Anyway, I was skiing off of far West baldy shoulder and I was coming down and was going to just do a simple 180 off of that cat track that goes along the mountain if you were to get off of Wildcat and go straight. I started skiing down and thought I was on the flat part when I was actually still going down the hill and then JOLT! I know for a fact my right leg was straight when I hit the cat track, then I skied across it still not being able to see anything I flew off of the edge unexpectedly and crashed. It didn't hurt too bad and I actually skied another run and didn't think much of it but today It hurts when I fully extend my leg and if I take a step and accidently over straighten my leg it hurts a lot for a split second mostly on the outer side of my right knee. I have it iced and it makes it feel better but then the pain comes back after a bit when I remove the ice and move my knee. I am not skiing today but I hope I will be able to tommorow.
