what kind of wood is this?

Came across these logs and need help identifying. My guess is either red oak or English walnut Anyone have any ideas?

So I thought this was a black walnut before it was cut down It was hard to tell with no foliage so I just went off bark. I included a pic of some bark from the mystery tree next to bark of some black walnut. Mystery trees bark is like an orange/yellow/brown combo After it was cut I could tell it...

Howdy all, I've been burning wood for a couple of years now but I don't know some of the firewood species yet, I was told this is mulberry but, when I try to look it up, what I find doesn't seem to match. I got this cord from a local sawmill for 60 bucks -- I've gotten wood from them before...

I live in Northern NJ. It is wood that I found set out on the curb throughout the season.
