So? We have found the same thing a few miles from here in NW Arkansas. I will be going by the dig in a few hours. It is being dug up, analyzed, examined, recorded. Then it will be destroyed because hwy 112 needs a round about at that spot. And yes, Hwy 112 is a very dangerous road.
It has happened before. On the La Plata Highway in Farmington NM, when widening that road a new Pueblo ruin was discovered recorded and then destroyed to widen the road.
So? It’s happened again.
Sort of a double-edged sword. If they weren’t building something new the old stuff never would have been found. Hopefully not too much of a delay in construction while still allowing for new information of the old stuff.
When the state of Washington was building a new floating bridge they did all sorts of historical research on where to build the floating pontoons and they picked a spot on tribal land and did preliminary diggings and determined that it should be free of artifacts. But once they started to build it was full of artifacts and it would have been too costly to use as a construction area so they had to find someplace else.
Rumor is that the indians knew that the area was full of artifacts and were hoping for the state to do all of the research for them and to pay the indians lots of money to do it.
