Whiteface/Esther is OK, a nice trip, generally.

Snowshoes or Skis must be worn in the ADK’s if there is 8″ of snow. Of course, this excludes mountain climbing, etc…there are always exceptions. So, I think your ski boots would be OK, but, these would do some bad things (post hole) to the trails if you don’t use your skis. Ice is common, so crampons or other traction devices are recommended.
Prepare for a minimum of -20F in the peaks. While Marcy was -146 (one HUNDRED and fourty six!!!) last week, this is unusual. Winter can be brutal in the High Peaks. Weather on many of the peaks can turn in a matter of an hour or two. Make sure to check before leaving. Always carry a map and compass! Put them in your pocket/on your lanyard around your neck. Whiteout conditions, visibility less than 10′ is common. Always carry two ways to make fire (a lighter, and sparker for example.) Slip these into your pocket, also. An emergency blanket (or two) is also highly recommended, more for an emergency shelter than a blanket.
