Data interpretation

A number of petroglyph panels were encountered in the Round Valley area during the Sycamore Creek project. Using the data provided, do these appear to demonstrate symbolism? If so, what might kind(s) of symbols do you think these represent? Does the location of these petroglyphs suggest that they had a specific function within local society?

I've attached 3 files that contains the data figures, data interpretation and additional information and instructions for the assignment.

Sorry for the confusion, since the assignment does not require additional sources as it is optional then no additional citation is needed. A SSA citation should only be made if you used additional sources. As for the png file referencing a 5 page assignment I do not recall sending a file stating that a 5 page assignment must be completed in MLA. What is the name of this png file? As the assignment should be around 500 words long.
