I'll see your Arizona Internet Object and raise you one Unidentified Ferrous Object in Utah https://ksltv.com/449486/dps-crew-discovers-mysterious-monolith-from-air-in-remote-utah-wilderness/?
Doesn't look like it has atmosphere re-entry damage, so initial assessments are probably correct that is a high altitude weather balloon or the remnants of another flat-earther exploration gone bad. The Utah monolith... pretty bad ass and someone is laughing their ass off right now.
I'm gonna go drive over and check it. If I'm not back in an hour then you'll know some shit went down.
