"The Yellow Rose of Texas" (1944)
Here's an oddity from the Roy Rogers/Dale Evans movie "The Yellow Rose of Texas." There's no mystery about where this shot was taken — the camera is just north of Garden of the Gods on the Lower Iverson, looking south toward Stormtrooper, the round-topped rock near the left side of the screen. But where that near-perfect "Man in the Moon" crescent came from, right in the middle of the shot, who knows? I've been all over that area and haven't seen it.
Here's a detail shot of Man in the Moon, which I've saved from the days when I didn't know how to annotate photos. It may still be easier for some readers to see it in this format.
