Any idea what's causing these circles in my gravel driveway?

I’m not ruling anything out including my all time favorite... Poltergeists!!!!

actually, my first thought upon viewing the pics was a bird dusting itself. Other suggestions also make sense... aliens break dancing?

I’d be more inclined to say birds vs a vehicle. Maybe kids and a leaf blower?

Animal urine after urine has evaporated?

My freightliner air brake release often made spots like that in loose gravel.

Moose urinating?

It’s from the exhaust turn down on a 1969 Plymouth Satellite, 383 2 barrel, bias ply tires, 4 door, white with a black interior, 727 torqueflite transmission, 180 pound driver, the spare tire is missing from the truck.

Do you have any pallets nearby?

Maybe a Wolverine urinated in the "O's" in Ohio last Saturday?

Is this an admission?
