Thanks! The huge termite mounds are in the same area of Litchfield National Park in the Northern Territory as the "magnetic" termite mounds. The first time I went to see them, I couldn't see what the fuss was about;
April was the end of the wet season, the grass was high, and the summer fires hadn't cleared it away. In October however, at the end of the dry season, it's a different picture altogether!
The termite mounds are aligned so that the narrow edge is exposed to the hottest sun in summer, while the flat side gets light when warmth is needed. So the design is in effect an air-conditioning system.
