I had no idea there were acorns that could be eaten without preparation. I'm not confident in my identification of the different oaks on my property yet. I know I have several. It's a lot easier for me to tell after the fact, when I'm splitting the wood. The deer really seem to like the majority of the acorns in the pictures. So perhaps they are white oaks. I have ordered a tree identification book for my state. I'm looking forward to reading that.
