The first time I saw a bur oak acorn (late 2018), I wasn't sure what it was. I wrote "Bur Oak Acorn, Walnut-sized Nut", and included my nutshell description: "The acorn had a bushy cap, like a short-dreadlocks hairstyle. The acorn itself seemed about the size of a walnut."
At that time, I had only a lone acorn sample. This time around, I struck a bonanza of two trees and loads of leaves and acorns. Read the entire article and comment there, please.
