Yes. Wachusett creates a field of these on the upper 10th Mountain Slope. They are perfectly symetrical - looks for all the world like a giant upside-down styrofoam egg carton. I think they do it for freestyle comps.
One time a few years ago, we had a large soft powder dump at night followed by a predicted picture-perfect sunny day. I headed up with the intent of catching freshies on the first chair, skiing into late morning, and heading to work for the afternoon. When I got there, the entire mountain appeared in front of me, bathed in brilliant sunshine - and groomed to flat corduroy everywhere! I didn't even bother to get out of the car....
You really can't blame them I guess - the average skier here just complains about ungroomed powder, and the heavy skier traffic quickly scrapes it off, so I think they pack it down to preserve it.
