Looking for 70/80's movie about Indian relics/artifacts?

Looking for the name of a mid-70’s early 80’s movie (possibly made for TV) involving the search for American Indian artifacts, specifically pieces of a golden tablet or possibly a stone tablet. The setting would have been modern day in the South West US, I just recall there were a white guy (probably an Archeologist) and an American Indian women searching for pieces of a golden table that were buried with tribal elders spread across the country. Along the lines of a tomb raider they may have had a map noting places to search, I know there were landmarks they knew to look for would indicate where a piece was located. I don’t remember the ending or what would occur if they found all the pieces of the tablet. I saw the movie when I was really young and it aired more than once on network TV. One other thing I thought of, the “landmarks” we’re actually symbols painted on canyon walls that aided in the location of the tablet pieces. I believe the lead Indian woman may have worn one piece of the puzzle around her neck. I don't recall any notable actors but this was not a Indian Jones movie or one of the Sinbad movies. Thanks for any tips!
