I will also go with sun glare - light refraction. Maybe where a spot of water dried. Looks like the sun is from that side. Nice pictures for a trail cam.

Let me guess, the sun is off to the left? It's internal reflections in the lens, aka sunglare.

Ooo! ooo ! Sun glare! What do I win? (awww shoot - I wasn't the first!)

Most likely sun reached the exact angle to show in your photo, wait several more days and as the sun moves the glare should also stop as the sun angle will be wrong.

Has anyone mentioned that it's "sun glare"?

Looks to be the literal end of the world; then again, that's just my interpretation.

If you can, take a series a couple minutes apart at the same time tomorrow. It should change position with the sun; if it doesn't it's probably a portal with the other end at Skinwalker Ranch.
