You guys know your Catskills. All the advice here was pretty accurate.
Lots of flowing water down low, 2-3' of snow up high, tons of frustrating fallen branches and snapped off treetops, some ice on the trail. You could bareboot most of the way but snowshoes were preferable for the deeper stuff. Surprisingly, I only saw one other group (out of many) on Slide and Hunter that even had snowshoes with them, much less used them. Lots of bareboot tracks and postholes.
I made it to both summits, although Hunter was a lot harder and took a lot longer than I expected due to trail conditions. Slide was a walk in the park in comparison and took me less than half the time even though the distance travelled was longer.
Thanks for the advice everyone, and hopefully my next trip to the Catskills will have better trail conditions!
