Termites - end of a civilization

What you see on the ground are the remains of a very large termite nest, which was placed in this very small tree. It was always the center of attention for visitors because it could easily be seen from the entrance to the Bosque. It had shown sign of abandonment over the last few months, so the termites knew what was up beforehand. In the next image you can see what it looked like when active and on the tree trunk.
