Is that the stream tagged with source = npe?  Just because you can't
see it from your armchair, doesn't mean that it isn't there. Although
I admit npe is often a bit approximate, and it may have dried up.
Maybe the NLS 2 1/2" historic map might shed more light.

Just ATM, I can't recall the right terminology, but these partially
collapsed sea caves are quite common, and I am sure I have seen them
with a dedicated tag. No doubt someone else will chip in the proper
tags.
