[Tenafly Nature Center, April 30, 2016] The morning was overcast and cold, with temperatures in the mid-forties, Fahrenheit. However, by afternoon, the sky had cleared to the stage where the clouds were isolated and puffy and the air had warmed up into the sixties. I walked in the Tenafly Nature Center, on the western flank of the Hudson Palisades ridge. I parked at the east end of Hudson Avenue, at the Nature Center parking lot, and walked to Pfisters Pond. It is a small anthropogenic impoundment, elongated in the east-west direction and with a very low dam at its southern end. The water by the outlet stream is open, with sparse lily pads, but the northern end is swampy. I walked two trails that followed the lake shore, one on the west side and the other on the east. I examined Skunk Cabbage, Trout Lilies and blooming Blueberry bushes. The deFillippi Shelter, a three-sided lean-to, is built along the eastern shore. I sat on its sunny porch for a while, listening to birds and spying the occasional Red Wing Blackbird fly by. I explored the woods a bit, walking a loop that took me past the pond’s exit stream, which was only sluggishly flowing. Back near the entrance, I stopped to examine a large patch of May Apples growing across from the John Allen Redfield Building. I then headed home. About two hours.
