The present log is very springy/bouncy. It's one of the worst in a long series of replacement crossings. I have brought the matter to the notice of the NYNJTC (I'm the trail supervisor for this section of the Long Path and wearing that hat as I write this) but the long and the short of it is that the DEC is convinced that the solution is a re-route, and I have the sense that this may take years to be accomplished.
There was a real bridge at this point some years ago, and there has been an endless succession of logs, but any crossing is exposed periodically to the combined force of the Deer Shanty and Neversink (one stream captured the other upstream of the crossing, perhaps within the last decade, which is probably why the bridge failed). The last solid crossing was erected by an ADK trail crew the summer before last. It lasted about three months, maybe less, before washing out.
This place is, in my opinion, an accident waiting to happen. I urge great care, especially at periods of high water. Anyone falling in then is not necessarily going to come out again. For that matter, a fall from the log at low water would be no fun. I suggest crossing about a hundred yards upstream, where there is a natural ford.
