One of the American west’s foremost plein-aire Impressionist landscape artists, Walters is most passionate about the historical cultures and varied, dramatic terrain of California, New Mexico and Arizona. Known as the greatest living painter of the Grand Canyon, Walters staunchly promotes its conservation, donating more than half a million dollars from sales of his paintings to the Grand Canyon’s preservation.
