“An ant mill was first described in 1921 by William Beebe, who observed a mill 370 meters (1,210 ft) in circumference. It took each ant two and a half hours to make one revolution.”
I’m curious where he found it. Sounds like quite a sight
Apparently, it was in a forest in Guyana. And well, perhaps you’re imagining a filled-out spiral, but in this case, it looked like a normal ant migration at the first. They were going in 6 lanes at most and at 370 meters circumference, that just looks like a line until you follow it around.

That’s according to this source, which seems to have excerpts from his book: https://themountainsarecalling.earth/the-army-ant-death-spiral/
That is fascinating. Thanks for sharing
