About those Mayans

(Who, by the way, are not extinct. I've met some).

Turns out there were a lot more of them than we thought. A LIDAR survey of Guatemala showed more than 60,000 hidden ruins, making a human-controlled landscape home to millions. It might indicate that Mayan civilization was akin to, well, Greece. Or China. The new estimation for the Mayan population - 15 million (before it was five million).

Most of the hidden ruins are fairly small stone platforms. That is to say: Houses. But they also found walls and fortresses, a seven storey pyramid (seriously) and raised highways that would have allowed trade to continue even during the rains.

But really. A seven storey pyramid...

IOW, lidar is awesome.
