It was a nice powder day at Timberline today, I went today because they just got dumped on, it was snowing all day, and it says it could rain Thursday. I haven't done a lot of hiking or cliffs to probably know the spots you speak of but I was thinking to myself, now I'm feeling why I heard it called Flatline. I did find some good trees, and a little gully to the right side of lower mustang meeting up with the Flood lift, I had a few good runs, but the snow was so deep that it seemed like I could never get any speed, anywhere, even on basic runs going straight the snow would slow me almost to a stop, I spent a lot of time traversing.
It was good and bad, powder half way up to my knees, some good tree runs, but I couldn't just go fast anywhere. Even on the groom, there was no reason to turn, if you did, you never had enough speed to get anywhere. I was kind of wishing I stuck with the Meadows pass. Only one more trip and it's worth the ticket price and it lasts until the end of May though. I'll give it a few more shots
