With the great weather we had on Sat., I decided to run a few tankfulls through the saw. The local spot where the city drops off most of the trees they cut down was full this time of year.  We spent solid 4hrs cuttin’ and loadin’ some of the heaviest/most dense wood I’ve seen yet. I’d like to know what kind of wood this is, as I’m sure it’s packing serious BTUs  

the bottom center pc was at least 150-200lbs

From the look at the colour difference between the sap and heartwoods and the varying textures of the bark, I would be inclined to suggest a maple of somekind…..possibly red maple.  Where are you located?

That one peice with the camo bark looks a bit like Sycamore, but the rest don’t.

If it’s Sycamore… good luck.  I hear that’s worse than elm.

I see one piece of sycamore.  The rest is out of my league.

thanks for the responses… here’s a close up of one of the rounds..

I only cut a few pcs of it as it was hard as a rock and after lifting the first pc…. we decided to leave it for another day… lol
dego, I’m in Ontario and after Warren’s post I found this:

Warren, do tell me more about it’s characteristics as firewood…. with it’s high density I was certian it would give off lotsa heat

Is it all from the same tree? Looks like some maple in there, but those pieces with the big hearts def. ain’t maple.

no, various trees… lot’s of maple (since it was much easier to cut… lol)
