Plane passenger takes a photo from the sky and later spots something NSFW

Can you spot it?

One passenger was flying over Denver in the US when, while innocently looking out the window, they spotted something unusual. The passenger snapped a quick picture of the ground from the height they were flying at, leaving the houses and people looking like tiny blobs in the distance. User Plebosaurus Rex uploaded the picture to Imgur, in a post entitled 'Found Something While Flying Over Denver', and the accompanying post appears innocent until the zoom button is used. The first picture appears picturesque, a gorgeous clear picture of the Denver countryside... However, it's only after zooming into the photo that a rude carving of a giant penis visible, just to the left of the plane's engine. No matter what age we are, silly drawings of the male genitalia will never fail to make us chuckle.
