I e-mailed the photographer to ask him how he made the image. Here's
what he said.

Ed,
The photograph is a stitching of 4 separate vertical shots taken side
by side, each photographing the night sky and landscape in one single
framed exposure with the exposure short enough not to blur the sky and
iso high enough to capture the stars, with a setting cresent moon to
light the canyon and artificail light to light the inside of the cave.
