Today, while we were in a wilderness area we frequent, I found what looked to me like chestnut burrs. I didn't have my camera, so I couldn't take a picture of the surrounding trees, but I did bring home one of the burrs.
Here's the thing: I've read that where we were, in the Pacific NW, there are no wild chestnut trees. So...what do you think? Is it a burr from a chestnut tree? Or could the burr be from some other plant/tree?
