30 Unusual Archaeological Finds In The US We Still Can’t Explain

15. TOOLS THAT WERE KEPT HIDDEN

A scientist in Oregon made a weird discovery on his property in the Willamette Valley. The cache of 1,000-year-old swords excavated shows they were stashed or hidden for later use. The makers made them with obsidian glass and the odd thing is, the blades were unfinished. Archaeologists suggest this depicts an ancient trade and the half-finished items were transported and swapped for other materials. It’s just a theory though, and it’s still unclear as to why they were unfinished and stashed away.
