After the last bad winter storm we had (2/2018) trees fell all over the park, including on my favorite hiking trails. Hemlock Hollow and Conservation Trails were grueling hikes this week, with a downed tree or 3 every 20 yards or so. There is cleanup going on, but it's going to be a while to make these trails relaxing and enjoyable again (as tough as it was, it was still enjoyable in hindsight… definitely not easy by any means, though).

ETA: 10/2019 The trail has been cleared since this storm and is a very enjoyable hike.  Kudos to ASP staff for trail maintenance!
