user: History of the Arches National Park creation.

Humans have occupied the region since the last ice age 10,000 years ago. Fremont people and Ancestral Puebloans lived in the area until about 700 years ago. Spanish missionaries encountered Ute and Paiute tribes in the area when they first came through in 1775, but the first European-Americans to attempt settlement in the area were the Mormon Elk Mountain Mission in 1855, who soon abandoned the area. Ranchers, farmers, and prospectors later settled Moab in the neighboring Riverine Valley in the late 1870s. Word of the beauty of the surrounding rock formations spread beyond the settlement as a possible tourist destination.

The Arches area was first brought to the attention of the National Park Service by Frank A. Wadleigh, passenger traffic manager of the Denver and Rio Grande Western Railroad. Wadleigh, accompanied by railroad photographer George L. Beam, visited the area in September 1923 at the invitation of Alexander Ringhoffer, a Hungarian-born prospector living in Salt Valley. Ringhoffer had written to the railroad to interest them in the tourist potential of a scenic area he had discovered the previous year with his two sons and a son-in-law, which he called the Devils Garden (known today as the Klondike Bluffs). Wadleigh was impressed by what Ringhoffer showed him, and suggested to Park Service director Stephen T. Mather that the area be made a national monument.

The following year, additional support for the monument idea came from Laurence Gould, a University of Michigan graduate student (and future polar explorer) studying the geology of the nearby La Sal Mountains, who was shown the scenic area by local physician Dr. J. W. "Doc" Williams.

A succession of government investigators examined the area, in part due to confusion as to the precise location. In the process, the name Devils Garden was transposed to an area on the opposite side of Salt Valley that includes Landscape Arch, the longest arch in the park. Ringhoffer's original discovery was omitted, while another area nearby, known locally as the Windows, was included. Designation of the area as a national monument was supported by the Park Service in 1926 but was resisted by President Calvin Coolidge's Interior Secretary, Hubert Work. Finally, in April 1929, shortly after his inauguration, President Herbert Hoover signed a presidential proclamation creating the Arches National Monument, consisting of two comparatively small, disconnected sections. The purpose of the reservation under the 1906 Antiquities Act was to protect the arches, spires, balanced rocks, and other sandstone formations for their scientific and educational value. The name Arches was suggested by Frank Pinkely, superintendent of the Park Service's southwestern national monuments, following a visit to the Windows section in 1925.

In late 1938, President Franklin D. Roosevelt signed a proclamation that enlarged the Arches to protect additional scenic features and permit the development of facilities to promote tourism. A small adjustment was made by President Dwight Eisenhower in 1960 to accommodate a new road alignment.

In early 1969, just before leaving office, President Lyndon B. Johnson signed a proclamation substantially enlarging the Arches. Two years later, President Richard Nixon signed legislation enacted by Congress, which significantly reduced the total area enclosed, but changed its status. Arches National Park was formally dedicated in May 1972.

In 1980, vandals attempted to use an abrasive kitchen cleanser to deface ancient petroglyphs in the park, prompting park officials to recruit physicist John F. Asmus, who specialized in using lasers to restore works of art, to use his technology to repair the damage. Asmus "zapped the panel with intense light pulses and succeeded in removing most of the cleanser".[19] In 2016, there was another vandalism event on Frame Arch in the park, where a section if the rock was carved out. Due to advances in technology, in 2018 the arch was repaired through color match and modern infilling methods.

assistant: First Humans appeared in this region during the last ice age 10000 years ago. The first settlers began in 1775 but were abandoned before 1855 when ranchers, farmers, and prospectors settled in Moab(the closest city to the Arches). The first attention to these beautiful rock formations was broad in 1923 by Frank A. Wadleigh. Devils Garden(known as Klondike Bluffs today) got its name from a prospector from Salt Valley Alexander Ringhoffer, Devils Garden was transposed to an area on the opposite side of Salt Valley. Landscape Arch is the longest arch in the park and the fifth longest in the world! 
In 1929, President Herbert Hoover signed a presidential proclamation creating the Arches National Monument to protect the arches, spires, balanced rocks, and other sandstone formations for their scientific and educational value. The name Arches was suggested by Frank Pinkely, in 1925. From 1938 multiple presidents of the United States of America signed multiple proclamations to protest scenic features and permits for road constructions in order to attract tourists into the area but only in 1972 Arches National Park was officially created. 
In 1980, vandals tried to destroy ancient petroglyphs in the park, which physicist John F. Asmus restored using laser technology for restoration. In 2016, another vandalism event happened on Frame Arch a section of rocks was carved, but thanks to technology, it was restored.
