Hi Jack,
I was wondering if you know anything about the lost ski area Holiday Hills located near Liberty Lake, Washington? I checked your lost ski area page out, but that was the only ski area you don't have any information about. However, I did some searching and found a satellite image of the area. I guess there was a Riblet double installed there in 1971, but chances are that it's not there today. It would be interesting to know when the place closed and where the lift went.
