It's ususally hard packed snow, not necesarally ice. I tend to ski real fast anyway, so I don't turn much. When it's icy I ususally just slide right over it. If it's an area where I want to go slow for whatever reason and it's real icy, I sort of just slide down the hill sideways, while digging the edges in. The edges don't really dig into the ice at all, but it creates enough friction to help slow you down.

Most of the time it's not too icy anyway. Lots of icy areas are in places where it gets a lot of sun and it melts a little during the day, and then re-freezes at night. During the day it tends to soften up though, so it's not that icy.

From my experience, the iciest places tend to be at the top of the mountain where it's colder. Mount snow has an area called "the north face". As the name implies, the north face faces north and doesn't get direct sun, most of the north face is also pretty high up in the mountain. This area can be icy. I think it's because on warm days the snow melts a little, then re-freezes, but this melting isn't from direct sun only warm temperatures. From December-March, the north face is probably below freezing over 90% of the time, so when it does melt and re-freeze, it stays as more of a permanent ice.
