I understand finding ‘shards’ of things and pieces that look like arrowheads or tools for scraping and cutting - but how could one ever possibly ‘make’ those last two perfectly oval stones?
How would one find river/lake/ocean shore rocks worn smooth when it was the Ice Age? Was there ANY open water?
Or is this a Quiz? ‘One of these things is not like the others.’ ;)
Typically such items have the signs of having been bound onto a handle, signs of wear from having been used to hammer stuff open, and remnants of goo.

Over millions of years there were may ancient streams and rivers that were later buried and become desert. So strata with layers of smooth Cobbles can be found just about everywhere in Ravines.
