Haven't been there for about a month. At that time there was ice, packed snow, and frozen packed snow. I got by fine with just yaktrax.
Some stretches in that area get icy and stay icy all winter. Generally they can be gotten around or over if you're careful.
After the snow earlier this week, I would guess that you'll run into mainly snow and packed snow, along with the typically icy stretches. If I were headed out there I'd pack snowshoes and instep crampons.
