Naples Mound 8
The Naples Mound 8 (also Naples-Russel Mound 8 or Illinois Archaeological Survey #PK 335) is a Havana Hopewell culture mound site located in Pike County, Illinois three miles east of the city of Griggsville. It is the largest mound on the bluff-top in the lower Illinois Valley. The mound was given the name Naples Mound #8 in 1882. The mound was listed on the National Register of Historic Places in 1975. First recorded visit by Mormon settlers In May and June 1834, Joseph Smith led a Latter Day Saint group of 150 men known as Zion's Camp on a march from Kirtland, Ohio, to Jackson County, Missouri. On June 3, while passing through west-central Illinois three miles east of Griggsville, Illinois, some men discovered a large burial mound on the west side of the Illinois River one mile south of present-day Valley city. Their report said that there were remains of bones on the surface and that when digging it up they found a skeleton about a foot beneath the surface, with a stone arrow point in the ribs. Through visions this was interpreted as a white Lamanite warrior named Zelph who was killed during a battle with the Nephites.
