Assets

• Sedimentary: chalk
• Flux: chalk, marble
• Sand: yellow, black
• Obsidian
• Three adamantite veins... and they're whoppers!
  Vein one: 24 safe Z's of mining
  Vein two: 51 z!
  Vein three: 53 z!![/li]

Open-air volcano, semi-flat... 9 z's of various plateus, 16 z cliff riding against the north boundary of the map... might be able to embark a square further south and avoid it, but probably not... it looks like there's one at the south side if you do that Nothing stopping you going 2x4 embark, though. Positive side: some good cliffs for entrances and lots of stone, though this map is NOT lacking for stone.

34 Z's to top of cavern (one cavern to save FPS)
40 Z's to magma sea

Almost all of these adamantite Z's are completely encased in semi molten magma, ie. you can mine the entire vein on those Z levels without running into conservatives. There is a LOT of the stuff for the taking. :3
