Lonnie Watson and Mark Louviere from the Ft. Worth, Texas metro area, discovered at least 10 figures, stretching over 60 feet of beach.

The petroglyphs are believed to be roughly 400 years old, and were created by aboriginal inhabitants of the Waianae coast.

Archaeologists from the Hawaii Department of Land and Natural Resources (DLNR) and the U.S. Army have been working together to record and document the petroglyphs; which now number at least 17 figures.

"They record our genealogy and religion," said Glen Kila, a lineal descendent of the aboriginal families who first settled in Nene'u on the Waianae Coast. His family home is a short ways from the petroglyph field.

"It's very important to know about the lineal descendants of the area and their understanding of these petroglyphs."
