A friend asked me to answer this question: What was the full name of the existing monument Horace Albright drafted a proposal to enlarge?, using the article: Zion National Park is an American national park located in southwestern Utah near the town of Springdale. A prominent feature of the 229-square-mile (590 km2) park is Zion Canyon, which is 15 miles (24 km) long and up to 2,640 ft (800 m) deep. The canyon walls are reddish and tan-colored Navajo Sandstone eroded by the North Fork of the Virgin River. The lowest point in the park is 3,666 ft (1,117 m) at Coalpits Wash and the highest peak is 8,726 ft (2,660 m) at Horse Ranch Mountain. Located at the junction of the Colorado Plateau, Great Basin, and Mojave Desert regions, the park has a unique geography and a variety of life zones that allow for unusual plant and animal diversity. Numerous plant species as well as 289 species of birds, 75 mammals (including 19 species of bat), and 32 reptiles inhabit the park's four life zones: desert, riparian, woodland, and coniferous forest. Zion National Park includes mountains, canyons, buttes, mesas, monoliths, rivers, slot canyons, and natural arches. Human habitation of the area started about 8,000 years ago with small family groups of Native Americans, one of which was the semi-nomadic Basketmaker Anasazi (c. 300 CE). Subsequently, the Virgin Anasazi culture (c. 500) and the Parowan Fremont group developed as the Basketmakers settled in permanent communities. Both groups moved away by 1300 and were replaced by the Parrusits and several other Southern Paiute subtribes. Mormons came into the area in 1858 and settled there in the early 1860s. In 1909, President William Howard Taft named the area Mukuntuweap National Monument in order to protect the canyon. In 1918, the acting director of the newly created National Park Service, Horace Albright, drafted a proposal to enlarge the existing monument and change the park's name to Zion National Monument, Zion being a term used by the Mormons. According to historian Hal Rothman: "The name change played to a prevalent bias of the time. Many believed that Spanish and Indian names would deter visitors who, if they could not..., what would be the answer ?
Mukuntuweap National Monument
