Alson S. Clark’s early paintings, such as Sunset Normandy, c. 1901, were greatly influenced by the works of James A. Whistler. Clarks’s work took on a definite Impressionist palette and technique, partly due to his exposure to the style of Claude Monet on a seminal visit to Giverny. Thousand Islands, painted c. 1911, shows this remarkable turn to Impressionism and the almost complete abandonment of Whistler’s influence. The painting is covered with a brilliant pattern of color applied in a lively brushstroke.
