When I was a kid in North Alabama I found Indian arrowheads in the cotton fields when we hoed and picked cotton. (Yes, I really did!) The only Indian I ever heard of (on the radio) was Tonto.
In Israel, ancient ruins are discovered as foundations are dug for new buildings or roads are being widened. It happened recently along Highway 38 at Eshtaol, the area where Samson grew up (physically) (Judges 13:24-25). Eshtaol is located about 10 miles west of Jerusalem as one approaches the Sorek Valley and Beth Shemesh. I have stopped several times for gas and water at the station on the left side of the highway.
Archaeologists working on behalf of the Israel Antiquities Authority exposed a site belonging to the Pre-Pottery Neolithic period. Buildings belonging to the end of the Chalcolithic period exposed a large standing stone (massebah) 51 inches high. The archaeologists said,
“The standing stone was smoothed and worked on all six of its sides, and was erected with one of its sides facing east. This unique find alludes to the presence of a cultic temple at the site”. … “In the past numerous manifestations have been found of the cultic practice that existed in the Chalcolithic period; however, from the research we know of only a few temples at ‘En Gedi and at Teleilat Ghassul in Transjordan”.
Todd Bolen discussed the identification of Eshtaol here.
