One of the Peak 8 carpet lifts (the one with a slightly steeper slope) is for snowboard use and the other is for ski use. Both are open to public use by folks who posess a lift ticket.
There are two carpets with really shallow slopes on Peak 9, one above the Village and one opposite Beaver Run. Again, if you have a lift ticket, you may use those. There is a third carpet on Peak 9 serving the Eldoro snowboard training area that is not open to public use.
There are platter pull lifts at both peak bases too, the one on Peak 9 being located between the two carpets and the one on Peak 8 positioned just below the top of the #7 chair lift (Rip's Ride). The slopes served by the platter pulls are slightly steeper and somewhat longer than the carpet slopes.
The other surface lift, of course, is the T-Bar serving fairly to considerably challenging terrain.
