The Story of Massacre – Mountain Meadows Monument Foundation

 . . . "All of the families were from Benton, Carroll, Johnson, and Marion Counties of Northwest Arkansas. After the 54 members of the Iron County Militia finished their grisly act at dusk on September 11, the bodies of the massacre victims were left exposed to the ravages of birds and wild animals"

The Victims – Mountain Meadows Monument Foundation    "A detailed accounting of the family victims, survivors, and estimates of property losses as a result of the massacre. This information was largely compiled by founding MMMF member Dr. Burr Fancher, gleaned primarily from relatives’ depositions."
