GOOD GRIEF ...I have never heard of anyone finding more than 2 Matates a day much less 3 and filming them, Excellent show.
That Gold point is a winner.
I've got a couple of small matates with that long narrow wear pattern also, I always presumed it was from grinding a particular type of plant ( herbs ? ) rather than just a style of working..
Since matates ( the heavier and deeper grooved the better )are sure signs of a camp a bit higher up....Are we expecting a follow up movie of digging that creek to bedrock ?
