At some point after the rock formed it was buried and saturated with iron rich ground water and the bands which are typically an iron rich mineral such as limonite precipitated within the rock in repeating rings. Later it was exposed at the surface and the softer sandstone eroded away leaving the harder rings standing in relief on the rock.
