I was just typing about Copper and decided to look at the new post before submitting. I was lucky enough to be there during a very large storm cycle and found lots of sheltered areas. The enchanted forest was really fun on the backside. Is the A lift on the far left of the mtn (lookers)? That was fun too. Sweet powder bumps on Mine Dump(?).When the wind starts blowing at Copper, I head for the A lift.
Others:
Chair 22 Mammoth - winds are ferocious at Mammoth and this closes sometimes but I swear its been open during 60mph!
Wildcat Alta - a little vertigo getting in there but then is awesome
Pali - A Basin - also a little exposed at the top but was barely able to make out a couple signs and sideslipped very slowly to them
