The round rock in the last picture doesn't belong in the area, I've found a few but I don't think they're anything but I pick them up regardless. The quartz doesn't belong either for the most part but I have found 2 quartz Heartbreakers here.
I find so many cores, preforms, scrapers and various tools here, this area is loaded with material. Some areas you have to move the material just to see the dirt. I think it was a manufacturing site, I've found plenty of points but nowhere near the amount as I have tools.
yeah, I realized I didn't add a dime or a quarter until afterwards but they're pretty good size, I do have a picture of the Hammerstone in my hand and it's close to the size of a baseball and I took a photo of it with some others up top, all pictures (except the bottom 2) were taken at the same distance.
