"Golden Spike National Historic Site ... A monument located near the site known as Chinaman’s Arch was renamed the Chinese Arch in honor of 19th century Chinese workers who helped build the railroad. The arch was likely formed by wave erosion along the shore of ancient Lake Bonnieville, a great freshwater lake that extensively flooded the eastern Great Basin region throughout Utah and Nevada."
