I need help with ID'ing a couple of trees - picture heavy

I've cut a bunch of these trees for firewood but am not sure what they are, I believe they first few pics are a type of elm. This is some of the wettest wood I've come across, the stumps will puddle water on top after cutting. The bark on the trunk is deeply furrowed and after drying for couple of months the bark comes off very easily.

Pic of the leaves.


Sprout with alternating leaves. Notice the chunk on the right - deep furrow on the bark.


Smaller branch. Some of the trees do not have as dark of heart wood.


This is another tree I picked up. One guy I showed the pictures to said it was a hackberry, but another said it was a choke cherry.




Any help would be appreciated. I can get at least for truck loads of the first type of tree, I hope this stuff burns well because I got about 4 cords of it.

I was thinking myself that second tree was probably cherry, but I am not good with tree ID's, yet.


Additional info:

The first tree I posted I see growing all over the Waterloo/Cedar Falls, Ia area.

I know the first is not a mulberry. I know it is not because I have a neighbor across the street with about 10 of these trees and never seen any berries or any bird droppings on my car to indicate otherwise.

The first tree, under the bark is real slimmey when green, and when the bark comes off it is black and smelly. From the descriptions on this board I've read, I am thinking it is Siberian or Chinese elm. I haven't burned any yet, hopefully it will be decent. I was told red elm is hard to come by and I see this stuff growing all over town.

I only had a pickup load of the second type of tree, but it is different than some cherry I got from a friend last year which he told me was black cherry. This cherry is much lighter in color and I think not quite as dense.

This is my second season burning and I had to buy some wood to get enough for this winter (which was not as dry as the seller claimed, not too bad though). I burnt some wood the previous owners left behind last winter, but only had enough for about 7 weeks of 24hr burning. I have 2.5 cords put up for this winter but I think I am going to be a cord short. I didn't get started cutting until June of this year and everything I got is still too wet. I have 4 full cords c/s/s for next year so I should be good next year. I want to get to the point were all my wood seasons for 2 years before I burn it.

I can get another 4 pickup loads of the elm. A business about 2 miles away is clearing a lot and I've taken 6 pickup loads out of there already. I like this stuff because it is close, splits easily by hand (mostly), and trees are mostly all trunk.
