This is a coastal scenery photo taken at blue hour on the California coast of the United States. The warm yellow full moon rises slowly from the dark blue night sky with lavender gradient, with a wisp of thin cloud beside it. The lower part of the picture shows a huge natural sea arch formed by long-term wave erosion. The tan layered cliff top is covered with low coastal vegetation. Under the arch is the Pacific sea surface with dark blue luster, and an isolated sea stack stands in the distance. The whole scene is quiet and vast, full of magnificent primitive natural beauty.
