2 Crawls, maybe not loggerheads

We had two false crawls this morning.  One was 39” at marker 66 and the other was 43” on the river in the Baptists.  Both these crawls were different from loggerheads but could not be positively identified as green or leatherback.  The one at the Baptists looked like a nest but after digging for over an hour no eggs were found.  We are labeling this as a Nesting Site.
