I was sitting at home noticing the light was changing and when I went outside I was blown away. I ran down the street with my camera and was so stoked to capture it before it faded! I think these are mammatus clouds? Photo taken on July 11, 2023 in Sandpoint, Idaho.

Camera: Nikon D750 Lens: 24-120mm F/5.0 1/640

I straightened the horizon in photoshop and that's it! This is the raw image with no edits!
