Lifer!
My lifer, not counting one that was found by a friend while camping in the Pine Barrens almost exactly a year ago (of which in any case I don’t have photos).
Based on the sparsity of observations of this species in the area on iNat, it wasn’t even a checklist item for the trip. Moreover, by this point in the day I had given up on seeing snakes entirely, and was only flipping rocks out of sheer compulsion while I hiked.
Based on this observation and another one later, I suspect that this species is in fact as locally abundant in the right parts of Harriman as it is in much of the rest of its range.
Second one of the day, which I’m counting as my lifer+1
