Sweet pictures.

Not proof, though, unless it was high tide in both photos. :)

I guess the articles did nothing to bolster my point.

How about these pictures then?

Fig.16 - The Ross-Lempriere sea level benchmark on the `Isle of the Dead' (made in 1841)
(photo taken by John L. Daly at mean tide, Aug 29, 1999. Benchmark is 50 cm across)

If you look at the shadows cast in each picture, both pictures appear to have been taken at the same time of day, ergo the tide level would be the same.
