Glacier Bay National Park in Alaska recently shared a rare mirage scene on social media.

The video shows that something that looks like a "flying saucer" in Glacier Bay floats on the water.

It is reported that this "flying saucer" is actually an isolated island in the middle of the bay. After being distorted by the "mirage" effect, it looks like it is floating on the water.
