I descovered this seed by accidante, like my other seed.

It features things like some really nice caverns, raviens, at least 3 abandoned mines, of which one is intersecting with the Stronghold! :D

And by the way, you spawn in a jungle. If you go south until you are in the plains biome and then west, you will come to the see. If you have gone correctly, you should see a small island, with the stronghold under it.
(The island is about 300 square blocks)
