Deer Valley Resort in Park City, Utah, has invested $9 million in improvements. The biggest change is the building of the Lady Morgan Express, a new high-speed detachable quad chairlift. It's in the Empire Canyon area. The expansion includes nine new ski runs, and more than 200 new skiable acres, including 65 acres of gladed skiing. Other improvements include the installation of a Snow Scan Ground Penetrating Radar, which is combined with a GPS system. It lets resort staffers know the snow depth on any part of the mountain so that grooming is easier. The resort also has purchased 51 new snow guns, replaced five Resort snowcats and 12 snowmobiles.
