I seem to remember, years ago, a similar "map" with islands,
mountains, seas etc. but in the context of nuclear physics.
I searched all the papers in my attic and can't find the source. Can
anyone help?
Thanks

There is a conjectured 'island of stability' up a few numbers in
periodic table.

The plot of binding energy against atomic number and mass number. The
main feature is a valley along the existing nucleus.
