We call them poplar. They do OK in the evaporator, but don't make a bed of long lasting coals. I sawed some to build a shooting house for hunters. If kept dry it lasts a real long time, if it gets wet very often it rots fast. I never used any to heat the house. As said above, it's an early successional species. In the spring they will send thousands of white clouds of seeds in a mild breeze. Something like dandelion seeds, but far more numerous.
I think your problem with the pictures is the distance you are from the tree. If you get one shot showing the entire tree and then one from much closer, just showing a section of the trunk others would more easily identify that tree.
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
