A dig report from 1992 flipped my view on pre-Columbian trade networks

I found a table of obsidian source samples in a dusty PDF from the University of Colorado's field school archive that proved people in the Southwest were trading 500 miles farther than I thought, has anyone else stumbled across old field data that contradicted what you learned in school?

Are you sure the samples weren't just mixed up in storage by accident?

Not a chance, @brown.susan. Those samples were CATALOGUED with timestamps and serial numbers, mixing them up would take a deliberate effort.
