It is clear from the 1976 photograph (though, curiously, not from the 1888 photograph) that what may appear to be a small lake here is in fact a hole. However, a dark outline round the hole remains, so that a lake was no doubt meant; without one, the Fl. Ambrvm (#10S) would lack a source. The lake (#6) seems not to have been named.
