I came across a herd of Rocky Mountain sheep a day earlier, but did not have a camera with me. I came back to the same spot next day, however was a tad late and couldn't find them- it was getting dark. However, when I was turning back I noticed silhouette popping up in a nearby cliff. Then the second one appeared and then another. It was a clear night with moonlight and bright stars in the sky. The moon is not in the frame and was able to capture star in the background.
