Ox Bow Lake Formation, As Seen By the Google Earth Time Machine 50
djl4570 writes with a link to this "excellent study in the gradual change of geographic features as a river meander becomes an ox bow lake when the river current cuts through the meander. The same Google Earth feature can be used to view changes in urban and suburban geography. The historical data is a work in progress. The region I looked at only has images going back to 1993. Other regions will have a different mix and depth of data."

This'll be a nice refresher, it was over 20 years ago and I don't remember a lot of it.

This article should be fairly significant for me, as I live right on the neck of a meander of a major river.

Full disclosure: I was in the movie
In the Science museum in Paris they have a wall with a crack that was closed when the museum was opened. They move the walls apart over the years by the same distance that Europe and America drift apart. There was quite a wide crack when I was there many years ago. By now you must be able to walk through it quite easily.

Over the course of your lifetime, Europe and America will have drifted about 20 feet further apart.
(Best estimate seems to be 5-10 cm/yr [uc.edu]. Split the difference and multiply by 75 years; that's about 5.6 metres.)

Plate motions world-wide range from under 1cm/year to about 14 cm/year maximum at the present time. Across the Atlantic it depends upon where you measure the spreading, because along any plate boundary the rates of motion will inevitably vary (it's a feature of motion on a spheroid), but the Mid-Atlantic Spreading Ridge is generally a fairly slow spreading ridge. 1 to 4 cm/yr relative spreading rate is typical. Between North America and Europe is probably 2-3 cm/yr, depending on which path you measure ac

The blog author provides the coordinates (and not a link) so you can view the formation on Google Earth not Google Maps. Google Earth has the timeline slider.
That being said, it's relatively easy to create a link to Google Earth [jalbum.net]. This should open the lake in Google Earth [google.com], if you have it installed.
