English: Mural 30, on the third floor of a rectangular tower (more accurately a room block) at Cliff Palace, is painted red against a white wall. The mural includes geometric shapes that are thought to portray the landscape. This mural is similar to murals inside other cliff dwellings, including Spruce Tree House and Balcony House. Scholars have suggested that the red band at the bottom symbolizes the earth while the lighter portion of the wall symbolizes the sky. The top of the red band, then, forms a horizon line that separates the two. We recognize what look like triangular peaks, perhaps mountains on the horizon line. The rectangular element in the sky might relate to clouds, rain, or the sun and moon. The dotted lines might represent cracks in the earth.
