id this tree

I'm not on the site, just this one log was brought to me.
Very heavy in weight.
Professional wood cutter says it is very hard to cut with his chainsaw.
That bark pattern reminds me of what we call cottonwood, white fuzzies like snow each May cover the city air (Sycamore?), but I have never scored one of those trees I wouldn’t think they are this dense/heavy unless it's all water, but as I say I have no prior knowledge scoring a cottonwood.
Was just felled alive today.
Thank you

Looks like sycamore

Bark looks like lacebark elm (Ulmus parvifolia) albeit atypical, but there is a lot of variability with lacebark elm.
Lenticels present and bark mottled.

Sycamore fast growing like poplar and cotton wood. See the large wide grow rings , means fast growth.

"Lacebark elm is tall, graceful and shady with a beautiful bark pattern that more closely resembles sycamore or London planetree than it does other elms."

(broken link removed)
Lots of bark variation between different lacebark elm cultivars, different ages, even within same tree. OP stated he just had this one log.
U. parvifolia is a very common landscape tree down South (the OP is from NC), but becoming much less common north because of hardiness issues and its susceptibility to ice damage.

Buds, or leaves would be definitive ID.

Sure looks like sycamore to me.
