The southern Utah site of a pioneer-era wagon train massacre is being dedicated as a national historic landmark.
The 760-acre (308-hectare) Mountain Meadows Massacre site becomes a monument on Sunday.
It marks the spot where 120 members of an Arkansas wagon train were shot and killed by a Mormon militia on Sept. 11, 1857. The Baker-Fancher wagon train was on a stop-over in the meadows on their way to California when it was attacked.
Officials, church leaders and descendants of survivors are holding a public dedication ceremony in the meadow 30 miles (50 kilometers) north of St. George.
Descendant organizations have worked for nearly a decade to elevate the meadows to historic landmark status. The Mormon church once downplayed its role in the massacre, but joined the push for landmark status in 2008.
