Joshua's Altar where excavation began in 1982, but not until now has its report been created. Kosher animal bones, the same design as the Second Temple Altar, and the right time period all denote the authenticity of the large altar structure found in the exact right place on Mt. Ebal.
Now, just recently a lead "Curse Tablet" has been found at the altar made of lead and engraved with the curse language of Joshua 8. And it's in Hebrew! And it mentions YHW (Jehovah), If authentic, this find could turn Biblical Scholarship on its head. It means the Israelites were a separate people from the Canaanites and provides archeological evidence for the Exodus.
