Today, I was able to get across the stream and do the longer loop trail, which was good, because there was another group of 4 walking around, and we needed to spread out. The longer loop wasn't yet broken, so I spent about 30 minutes breaking trail in 8" of fresh soft powder. When I got back to the stream, I followed some previous tracks up the frozen surface, and eventually came to the main attraction, the waterfall at the head of the valley:

By now, the other group was also here, so I didn't hang around long. Walked to the base of the falls and peered behind the ice, took a few pictures, then meandered out, again breaking trail most of the way. It was a good 90-minute workout.
Another 5-10" of snow is expected tonight, followed by a major thaw next week. So goes March in the northeast.
