Well looking at all the spalls, you definetly have a site. You'll prolly find more blades/knives than points, looking at the pile of spalls & flakes. These are an indication the rhyolite was brought in from another area & blades, points were actually knapped on your site.
I too found lots of spalls but more so blades/knives,preforms,about 30 in total this year. I'll be surprised you don't find caches of blades.
Looks very promising, I'm excited for you, Good Luck. Let us know how things go. Also check surrounding fields too, I found not only was there points/blades on the campsite but surrounding fields too.
