I'm sure Sierra Cement is much harder to clear out than Utah Champagne Powder! I remember in the winter of 82-83 skiing at Kirkwood when the chair rode along the snow due to the high snowfall amounts during that El Nino winter.
Nice to see the KT22 chair skimming the snow surface. I remember many days there of dumping snow when only the lower mountain was open doing laps on KT-22. Most fun ski lift in the world.
