Grinding Seeds


Along the dried river bed where the petroglyphs are I discovered these holes in the rock where the early inhabitants to this area ground seeds.  Try to imagine how much grinding took place to wear holes in the rock this large.  The rock surface is level. it just appears slanted from the way I took the photo.  Hopefully it was nicer times many hundreds of years ago and water was flowing in the river.  My this just hurts my back thinking about sitting here pounding rock against rock.


The one on the left was the largest and over a foot deep.

  1. That looks a lot like the cauldrons that can be found in rocks in dried up riverbeds in Sweden. I'll look for pictures of a few - and they were created by rocks that became stationary during a time when the river took a different route and the water made certain rocks go round and round in the same sport.

    1. I have seen these water created holes you mentioned in several places during our travels. Yosemite above Nevada Falls for one and most recently near Moab, Utah.

  2. How interesting! I wonder if the deeper hole was used as a cooking pot? Hot rocks could be added to boil things. I have seen similar indentations in west Texas. Mesquite beans were ground to use like we do flour.

    1. On a trip years ago we were very near the State Park but didn't go. I don't recall why. Maybe next time when in the area.
