of the country's few female architects – and arguably the most outstanding – Colter worked in often rugged conditions to complete 21 landmark hotels, commercial lodges, and public spaces for the Fred Harvey Company, by then being run by the founder's sons. Fred Harvey developed the West along the Santa Fe's main route through strategic use of restaurant efficiency, clean-cut and pretty young women, high-end tourism, and quality souvenirs. Anthropologists on his staff located the most appealing Native American art and artifacts like pottery, jewelry, and leatherwork. His merchandisers designed goods based on those artifacts. And in strategic locations, Colter produced commercial architecture with striking decor, based on some concern for authenticity, floorplans calculated for good user experience and commercial function, and a playful sense of the dramatic inside and out. The Santa Fe railroad bought the La Fonda hotel on the plaza of the old city of Santa Fe, New Mexico, in 1925 and leased it to the Harvey Company to operate. For a major expansion, Colter was assigned to do the interior design and decorating. She hired artists and artisans from the nearby pueblos to make the furniture. Native American styles were employed in hand-crafted chandeliers, copper and tin lighting fixtures, tiles and textiles, and other ornamentation. La Fonda became the most successful of the Harvey House hotels. Its striking blend of Pueblo people and Spanish artistic influences, today known locally as the Santa Fe Style, became very popular across the region. Grand Canyon buildings Colter created a series of remarkable works in the Grand Canyon National Park, mostly on the South Rim: the 1905 Hopi House., the 1914 Hermit's Rest and observatory Lookout Studio, and the 1932 Desert View Watchtower, a rock tower with a hidden steel structure, as well as the 1935 Bright Angel Lodge complex, and the 1922 Phantom Ranch buildings at the bottom of the canyon. Colter also decorated, but did not design, the park's El Tovar Hotel. In 1987, the Mary Jane Colter Buildings, as a group, were listed as a National Historic Landmark. (She also designed the 1936 Victor Hall for men, and the 1937 Colter Hall, a dormitory for Fred Harvey's women employees.) Colter worked with Pueblo Revival architecture, Spanish Colonial Revival architecture, Mission Revival architecture, Streamline Moderne, American Craftsman, and Arts and Crafts Movement styles, often synthesizing several together evocatively. Colter's work is credited with inspiring the Pueblo Deco style.
