Was it the quartz Morrow Mt, if so Quartz points don't always show knapping, just the way the material is, also the knapper, I have only one Guilford-Milky Quartz, that shows excellent knapping. So I guess quartz would be difficult to ID, so one must rely on bases,points,grinding n such. I've said this before, I find lots of rocks that look like points but are not, no flaking,no points, no bases, no grinding (if there is a base). One could end up with just lots of gravel. I have been taught by two museum guys, who have hunted & collected for many many years, they are the best Artifact collector & typologists I know. I used to be showing them rocks all the time, got frustrating to hear them say Nope, just gravel. But it taught me a lot, stick to the basic rules above & you can rest assured that you have Indian Arrowheads.
Just my opinion.
