Not sure of either of these scrap pieces. Two have very definitive rings around them from the center out, like a bullseye. Very light color to them. The bark and color is noticeably lighter than the black walnut from yesterday I posted. They are actually on top of the walnut, so if you look closely, you'll see how they vary in color on the bark and heart wood. The 2nd piece of wood has a little junk around the edge (about an inch), but mainly good wood. I can't tell if it's sassafras or not because I smelled too much and my nose needed a break. The piece is toward the base of the trunk (same piece, two different pics). Thanks gentlemen!
