Natural Photographer Jeff Templin captured the image around 2014. A Reddit post surfaced explaining what could be in the photo.

 The image captured was most likely a military aircraft in testing over the Amarillo area. Most people reference the aircraft to that of a B-2 Stealth Bomber. Bombers are often mistaken for UFOs according to an article by the Huffington Post.

Templin described what he saw while taking the photo.

Right over the city, clear as a bell. Anyone that was looking up would have seen it. You don't usually see military or even civilian aircraft's jets that leave contrails making those kind of severe departures off of the given route. [It was] Absolutely silent, no sound. When I put it on my computer and processed them, I was surprised to see this triangular shape that is not like anything you typically see. It was one of ours or at least man made for sure, so unidentified yes, but alien, no.

What's interesting is the aircraft must have been a new design being tested. While we don't know the exact name or model of the aircraft, we ran across a site that might have more information.
