Was a massive root system discovered under Devils Tower, a geological formation designated as a national monument in Wyoming? No, that's not true: A spokesperson for Wyoming State Parks confirmed that the claim originated from a satirical social media post.
The claim appeared in a Facebook post (archived here) published on July 6, 2021. The post featured a picture of Devils Tower and a diagram of an extensive root system. It opened:

Lead Stories could not locate any statement from Wyoming State Parks that matched the one included in the post. During a phone call with Lead Stories on July 7, 2021, Gary Schoene, public information office manager of Wyoming State Parks, said:
The outlet that published that is similar to The Onion. It's called Casper Planet. So no, it's not true.
As of July 7, 2021, the About section of the Casper Planet Facebook page read:

The Casper Planet version of the Devils Tower claim was debunked by Snopes in 2017. The debunk located the original version of the root diagram, which turned out to be a diagram of root growth in sweet corn and determined that the satirical post's purpose was to mock a flat-Earth conspiracy theory.
