This site features
-A nice river flowing through it
-A chasm
-A bottomless pit
-HFS!
-Magma pipe extending to the surface
-Underground river
-THREE different sets of surroundings, you get Terrifying, Untamed Wilds, and Wilderness all rolled into one site!
-Despite having only a small amount of non mountain terrain, this site has TONS of trees.
-Yellow sand and red sand!
-NO aquifer at all!
-Poking around with Reveal showed me Hematite, Native Gold, Copper, and Platinum in large amounts.
-Cave spiders for silk
-Access to all 5 Civilizations (please note I have the Orc mod installed)
And here's something I've never seen before. If you pick the 2nd Dwarven civ as your starting civ, the Goblins will be actively AT WAR with you!
Here's a better picture for you guys.
Well, whatcha think?
UPDATE - Some pics of the site for you.
You can see all of the major features here, and how plentiful the sand is. The river carves a canyon out of the mountain in the lower left.
This is a few Z-levels higher, just so you can see to the left where the trees are. They're actually quite plentiful in that small area. And there's a few small ponds as well.
