I like the big shallow circular matate/mortar front left. Definitely a style going on at that site or area, if they are from the same vicinity, lots discoid shaped grinders/pestles and shallow work surfaces. Is the reddish triangular metate complete or is that a fragment? Those big lighter colored basalt(?) pestles are nice.
I enjoy thinking about all the activity surrounding those metates and mortars. Women cooking, chatting, & kids running around everywhere. Makes you wonder what foods were being prepared. I'm sure there were problems & things not pleasant back then but not so sure we've improved our human condition as much as we like to think we have.
Here are a couple of early woodworking tools, a wedge and and adze. Thanks to those who helped to indentify the wedge in an earlier thread months back. That one had puzzled me for years.
