Years ago I was hunting in an area of NE NM and since the are is soil and a gray shale, the red and white rock stood out. As i looked I found lots of chips and fully finished scraper about the size above lying there. Wonder what caused someone to forget it and abandon the "mother stone" there. found a shale arrow head int he same area the same day. Amazing how a piece of worked stone jumps out of all the other pieces of native rock lying there.
