What expert run(s) would you hit first?
Yes, THIS!!! Got a great powder day on my first trip to Colorado back in 1983 and spent all morning there.
The Whale's Tail.
Watch for openings of the T-bar, Imperial Quad, and Chair 6. All are likely delayed on a powder day for avy control. Chair 6 is likely to open first and gives you access to the Imperial when that opens.
