Some of the maps reflect very narrow windows of time. For instance, the whistler map covers the time after harmony bowl opened but before the peak to peak gondola. I think that places it in the 1999-2005 era. That was a great time, back when normal people could afford to ski regularly. Although taking harmony bowl away from the "backcountry" skiing community by putting a lift on it was not good.
