Well since it was Saturday I found myself extremely bored and wanted to push the limits of teraforming. Decided to go with a man-made mountain that took an afternoon of digging. I set out to have the plot be 12x12 squares, but the task started to become too laborious. With a certain height I found that it required a new tier to be built in order to not destroy the 1st tier. The square staircase goes counter clockwise up to the very top where you have a nice view of the neighboring tribes. Enjoy

Where I had to stop building straight up and finish a flat tier:
