Stone tool working table?

[Ed144]

I've been exploring an area known to have more than 3000 Hohokam era petrogylphs. This stone "table" is on a ridge that has ancient camp sites, caves under boulders and hundreds of petroglyphs. Does anyone know what this stone table was used for? It appears to be worn on top over most of the surface and has 16 or more small divots worn into it. The rock is about waist high, more or less flat on top and about 3' in diameter. I was standing on top of another boulder to take the photos. Perhaps it was used to grind something small that would accumulate in the divots? Could it be for working hides? Thanks for any comments. Ed, Arizona.

It could have been utilized as a food prep station.
