**** Going to insert my description of the map as posted to Reddit, easier that way ****

Yesterday I was puttering around and working on starting up a new fortress, generated a new world map 65X65 - Low Population - Low Sites - High Savagery - Low Beasts - High Minerals... a good map to experiment with for beginners so I could work on waterfall generation and millitary design.

Imagine my surprise when I generated the world and looked through the map and discovered what I consider the perfect tile. A 4X4 split elevation map that's peaks (not just mountains, we're talking the mineral soaked 400 elevation bad boys) on one side and temperate plains on the other.

This would be an uncommon start area to begin with, but imagine my surprise when I got onto the actual map and discovered that it is PERFECTLY bisected.

That's right, half of the map is a perfectly flat plain dotted with trees, lakes and foilage... and then it suddenly shoots vertically upwards 15 or 20 Z levels in the span of a dozen tiles. The rock wall is perfectly straight all the way down the middle of the map.

This bad boy even has sandy soil, an infinite source of glass given that half the map is dense with trees.

I embarked with plenty of food, plenty of booze, and enough malachite and cassierite to make 10 units of bronze weaponry. I have 6 proficient miners (I'm starting on a mountain after all) with carpentry, masonry, mechanics, glassmaking, metalcrafting & weaponsmithing respectively, and one 'leader' with brewing, leadership, appraisal, record keeping and organization. The only things I've done so far are make my picks and axes from the ore I brought with me, flatten out the ramp/slope down the center of the map and dig out the first couple rooms of my base, see the screen shots to get an idea what's been done.
