I just realized that this has been lurking in drafts for quite some time - thought I was going to write more but I think I'm just going to post it!
Today in Yahoo Science - the Hawaiian Islands you've never heard of (with at least one notable exception).
You've heard of the inhabited ones - Hawaii, Maui, Molokai, Lanai, Kauai, Ni'ihau, Oahu. You may have heard of one uninhabited one in the same area - Kaho'olawe. But there are actually a lot more in the chain, which has been created as volcanoes arise at a hot spot in the earth's crust, then drift in a northwesterly direction with the tectonic plate of which they are a part. These are known as the Northwestern Hawaiian Islands, and they've just been declared a new refuge area. You actually probably know the name of, at the VERY least, one of these islands - that would be Midway (as in "Battle Of") Atoll - but as an actual continuation of the chain of islands that makes up our 50th state, I don't believe they're really well known.
Also very worth a visit (particularly after the Yahoo link quits working, which they do eventually) - here's the website for the refuge itself - interesting reading!
