Canadian Rockies (Lake Louise) ca. 1889 Albert Bierstadt American During his travels in the American and Canadian West, Bierstadt made oil sketches such as this one, which he used, back in his New York studio, for reference in concocting the huge, carefully detailed panoramic scenes that brought him critical acclaim during the 1860s and 1870s. By the end of the century, American viewers had come to appreciate the more modest landscape observations of Barbizon and Impressionist painters, and Bierstadts sketches were themselves valued as fresh, direct records of the places he had visited..
