🙋 I saw this too

My dad found this while looking through old photos. The mountain is the Half Dome in the Yosemite, pic taken around 2016/10/21 at 10am. Any ideas?Yosemite, USA · Oct 21, 2016 around 10:00

Did you see the same thing — or something like it — at the same time? Add your own account. Several independent witnesses is the strongest evidence a sighting can have.
