Hit this joint in January 2018 when it was 1 month old. As expected, all the infrastructure was brand spanking. Resort and on-mountain eating are very upmarket. Our one day there was sent from the heavens: deep, deep powder and bluebird for most of the day. Words cannot do the day justice; probably the best single day's skiing of my life and I've been skiing since 1969!! Wow!! Just wow!!
