How to find mountains in the fog...

I've found that if you use the signal feature (INSERT), and click on the black areas of the map, mountains show up. They cause the ripples from the signal to be slightly distorted in one way or another. By quickly flashing around your starting city, you can find any mountains nearby, and place your second (or third) city near the mountain.

As my friend Mark has just pointed out to me, if you are in a co-operative game against the computer, or a group battle against another, a less annoying way to find the mountains is to build a building. But before you place it down somewhere, move it around on the screen. It will show the contour of the mountain as you move it over and around the mountain.
