What compass direction are the mountains?

In my mind, the mountains are to the north, and we are viewing the town from an angle. This is based upon the obvious fact that all the buildings are at an angle and additionaly most roads in standard, simple towns typically run north/south or east/west, not nw/se or ne/sw. Then again, part of my job involves property appraisal and township lines and stuff like that, so Im used to looking at maps.

Additionally, the icon used to move buildings around looks like a compass arrow thingie, but at an angle.
