If you thought your winter was hard, imagine living on top of a rock all winter, exposed to the wind the whole time. On top of this Catskill boulder we see Polypodium virginianum, rockcap fern, one of our evergreen ferns, and what looks like a very sad and droopy Dryopteris. Catskills Dryopteris species remain green during the winter, but their fronds are typically flattened down by the snow. Here they are hanging down from their pocket in a sheer rockface. Covering the rockface is a moss, fern moss to be precise, Thuidium delicatulum.
