From Mckinley Hollow the trail is hard packed snow and ice.
Crampons are veryu helpfull.
Then on the pinehill-west branch trail the snow is hard packed but deeper. You can get away with crampons but snowshoes will give you more stability. It snowed on and off all day, The temp was in the teens with a very strong wind. Most snow that did accumulate blew around. When I left it was still snowing.
