What a great thread on trees, acorns, and all! Love all the info!

While on a camping trip recently I was walking along a river in upper Arkansas and came across some HUGE acorns. I just had to gather a few to bring home. (We don't have them this big in NC, that I know of anyway.)

The tree was growing on the bank of the river but I wasn't able to recognize it as any oak we have here.

Does anyone know what kind of oak tree would begat such huge acorns? (In the pic, that is a dime, not a nickel, for size comparison.)

Shoe.
