I first saw that on one of my favorite TV shows called “What On Earth?” where they investigate strange, anomalous images that pop up on satellite photos.
They had to actually fly part of the way and then pack in, to see what it really was.
It is *huge*.
[and part of me giggled at the thought of your liberal neighbors having *that* pop up in their world]
Gotta tell you, it was wild. My brother in law had a place there, and I wouldn’t have known about it, except I would go over to his house over the years, and the water came up into his back yard, over an expanse of land I wouldn’t have expected! He told me the whole sordid tale!
