Never knew Hard maple could get those flecks. Have a cache of sugar maple turning blanks and no flecks in that Of course there are a few other hard maples.. The lines between growth rings look a little open for hard maples I have worked with.
If while turning it you get an urge for pancakes, then it's maple.
There are a whole bunch of maples and most are not "hard maple". I agree it's a maple but not the sugar variety of syrup renown.
Are you able to find any of the branches to look at? Maples are one of the few trees that have opposite branching.
TIP: Use the mnemonic "MAD Bucking Horse" to help recall the most common trees having opposite branching which are Maple Ash, Dogwood, Buckeye and Horse Chestnut.
