California printmaker Micah Schwaberow studied color woodcut with Japanese woodblock artist Toshi Yoshida in Japan.
"Nightfall, Gualala River" depicts the mouth of the Gualala River in northern Sonoma County in California, where it empties into the Pacific Ocean. It forms part of the boundary between Sonoma and Mendocino Counties.
Schwaberow captures the last minutes of the sunset, after the brilliant colors have died and dark descends. He uses the grain of the woodblock to create an atmosphere in the sky and a ripple effect on the surface of the river.
