The rock outcrops were further enhanced with parallel lines from the small set of colors previously used, but the overall appearance lacked definition. Small check marks were added in a neutral gray, which echoed the color used in the sky, and represented those (mist dampened) edges which caught the light and broke up the smooth run of rock.
When viewed close up, they look almost random, but from a distance the rock outcrop now looks slightly fragmented and worn.
