Greetings, per my previous post where I misidentified evil wood as locust, I wanted to provide more images of the mystery log. I took some of the end grain as requested, and can tell you one more detail. The raw wood has a pleasant, not-fruity odor, but hard to describe. It doesn't smell sweet and watermelon-y like maple, and doesn't stink like red oak. It almost smells like it could be a 'savory' flavor.
I'm not going to eat it, I swear. Anyway, here are the images:
The bark is very thin. It does not come off without effort.
This gives you an idea of the size and shape. It's pretty heavy, probably about 30 lbs for a four-ish foot section.
