History

The rock derives its name from the fact that it lies directly along the route of the Emigrant Trail. Pioneering wagon parties bound for

usually left the Missouri River in the early spring and hoped to reach the rock by July 4 ( Independence Day in the United States), in order to reach their destinations before the first mountain snowfalls. It was likely named prior to 1830. John C. Frémont camped a mile below this site on August 1, 1843 and made this entry in the journal of his 1843–1844 expedition:

Everywhere within six or eight feet of the ground, where the surface is sufficiently smooth, and in some places sixty or eighty feet above, the rock is inscribed with the names of travelers. Many a name famous in the history of this country, and some well known to science, are to be found among those of traders and travelers.

Fremont carved a large cross into the rock monolith, which was blasted off the rock on July 4, 1847 by hundreds of California and Oregon emigrants who had gathered on the site.''Wyoming: A Guide to Its History, Highways and People (American Guide Series),'' Native American Books Distributor, 2007, pp. 386-7 Some Protestants considered the cross to be a symbol of the Pope and Catholicism. John Frémont was actually a member of the United States Episcopal Church.Bigelow, John, ''Memoir Of The Life And Public Services Of John Charles Fremont,'' Kessinger Publishing, 2006, p. 465 On July 4, 1862, Independence Rock was the site of Wyoming's first
