History of the Arches National Park creation.
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.
