Summary
[edit]DescriptionGrand Canyon National Park- Powerhouse (2014) 8312 (13204270244).jpg |
The Grand Canyon Power House was erected in 1926 by the Atchison, Topeka and Santa Fe Railroad (ATSF) to supply power and steam heat to Grand Canyon Village. The building was designed by ATSF engineers in Los Angeles in the Rustic Swiss Chalet style and constructed by James Morris of Flagstaff. Originally the Power House had a 160' high smokestack visible with the naked eye from the North Rim. In 1935 the Power House was upgraded with two new Fairbanks-Morse diesel engines, which remain within the building. In 1956 Arizona Public Service brought power lines to Grand Canyon, removing the need for an independent power generating facility at the South Rim. The stack was demolished and the boilers were removed prior to the Fred Harvey Company taking over the building for use as a warehouse. In 1958 the Fred Harvey Company built out the interior, installing offices and refrigeration equipment. In subsequent years the loading docks were altered and additional openings punched in the walls to accommodate new entrances and ancillary functions, A large mezzanine level was installed in the interior of the Power House to provide additional office and storage space in 1964. In 1998 an additional fire exit was constructed on the south wall of the building. |
