Temple of Moonlight
What you are seeing is a vertical panorama of moonset through the famous Pfeiffer Beach archway in Big Sur. The moon was fairly dim during this phase (18% or so) giving slight visibility to the Milky Way overhead. As the moon dipped down closer to the horizon the Galaxy became visible enough to even see some subtle nebula colors. The panorama consists of about 5 shots overlapping starting from almost completely overhead all the way facing down at some rocks near the tripod legs.
