Lots of downed trees, spruce traps, etc. Trail blazes are buried under snow in many places. Don't follow the trail I broke, it wanders in circles at times for a reason.
Snowshoes are essential given the snow depths, trekking poles very useful.
Broke trail to the top of Mt. Wolf. Lost the trail near the summit of Mt. Wolf. Tried to bushwhack to other side, in hopes of picking up the trail but ended up at the bottom of a 6ft hole, snowhoes hopeless tangled in spruce trees. Planned on staying at Eliza or Kinsman Shelter, but had to retreat to the car when it became clear the trail wasn't navigable.
