"If you visit the  Churchill, Manitoba region of Canada, you will find a spot
where the British  Navy installed a very large iron ring into the rock for
mooring ships. This  was done around the 1700's. When it was constructed, it
was, according to  our guide, right at the shore. Now it is a few hundred
yards away from the  shore. The isostatic rebound in the Hudson Bay area is
quite dramatic. I  wish I could remember more details about the spot but it
has been close to  30 years since last I visited it."

Even better, if you could remember how  it looked then and go back... thirty
years is long enough to show significant  change on a gently-sloping shoreline.

In the Mystic River, a mostly  saltwater estuary, where Mystic Seaport is
located, there is a mud bank known as  "Bill's Island" (I can't remember the real
name --I'm using Bill as a  placeholder). It's pretty easy to get your boat
stuck on Bill's Island since  it's only about a foot below the water level at
an ordinary low tide. I remember  when I was a kid, maybe in 1976 at the time
of the Newport tall ships thing,  visiting a small Danish square-rigged vessel
that was stuck on the  "island".  Most of the time, the island is not visible,
but when there's an  extreme astronomical low tide coupled with high air
pressure and a strong wind  blowing out, it lies high and dry. The locals mostly
believe that refering to  this place as an island is an ironic joke. It's
underwater, and obviously not an  island. They're not aware that it once really was
an island. It's marked on  mid-19th century maps, and in almost every photo
of that area in the later 19th  century, sure enough, there's Bill's Island. A
foot of sea level rise in a  century isn't much when measured up a pole, but
sometimes you can find evidence  of it...
