Is this American elm?

Alternating leaves, and the bark looks a match, I'd say american elm!
 
Thanks so much guys! After all your posts I don't even know that I care to colect a seedling anymore. I kind of want to get a hold of a decent trunk and try my first broom style with one of these. Save myself a couple years
 
If both the upper and lower surfaces of the leaves are rough and sandpapery, it is a slippery elm, which is also a great native tree!
 
@GGB to tell if the possible parent tree is American elm break off one of the flakes of mature bark. Then break it in half and look at the layers of bark. If it is striped red and white it is American elm; if it all red it is slippery elm.

Took a different route today and I believe I found the parent tree. So what's the verdict @Giga?
Dude, FWIW, having worked with Zach Smith for going on 25 years, I'd say his opinion on native trees is pretty definitive. He's dug more of this species than anyone here...Just sayin...
 
Thanks again, I'll check both sides of the leaf tonight and snag a chip of bark
 
I had one little sprout come up in my grow bed a couple of years ago, and it already has nearly 1" trunk. I have no idea where it came from. The roots are so prolific they'll grow up your nose if you stay in one spot too long.

True but I have a few american elm and this matches from the pictures provided, alternating leaves, bark match, reddish tip. I use to live in PA and familiar with native species as most my tree's are native. I always love a second opinion as well as were not always right. Once he gets the leaves and bark we can be 100%

Yeah, it's definitely American elm. You can watch for those ground-level shoots or any fast-growing branch and you'll see often quite-large leaves, up to 5" in length, with that classic extended tip and the asymmetric sides. I think American elm has the largest leaf of any native elm ... but they reduce to under 1/2" with diligent pinching. I call it the champ for leaf-size reduction. Wonderful for bonsai.

And they grow like a mad man! If I control growth to one leader it can easly push 18 ft in one year

I pruned the roots on mine very aggressively this spring. It had a lot of large roots that I wanted to cut back to start building a nicely ramified root ball, but it left few feeder roots. Frankly, I wasn't sure if it would even survive. Not only did it survive, but I was pleasantly surprised to find that the leaves reduced very nicely, to 3/4" or so. This was not my intent, because at this stage I want big power leaves, but it showed me that leaf reduction is possible. Leaf size this year was a sacrifice to get the roots going. So, the first priority is a good root system, while allowing undisturbed growth.

So maybe a seedling is an okay place to start? I'll be walking past the mother tree again today. I thought the ground was littered with seedling but they're actually all suckers

I started with a seedling 3 years ago and cut back each year now I have a tapering trunk of 4" at the base and growing
 
I did the bark test today and it was red the whole way through, @CasAH said that was an identifier for slippery, and both sides of the leaves are fuzzy.
All the "seedlings" were in fact suckers. But I found a little guy growing up between the side walk. Regardless of the species I'm happy to jump into the genus. Slippery elm is still a PA native, I did notice there was a whole row of purposefully planted elm trees. It seems weird to me that a land scaper would choose slippery elm over american.
 
It's American Elm due to the shiner leaves and more pointed teeth
