Just a FYI - there is a American Chestnut tree (see sample of leaves/nuts below)
We have a few of those around here in Middle TN. I found a real nice one growing on a bluff I was hunting seng on last fall and brought home a pocket full of nuts. They are sweet looking (almost polished looking) and are not bad to eat either.
But the sprouting acorns that were shown in this post are not from the American Chestnut tree - they are from a Chestnut Oak Tree - also called Rock Oak, Mountain Oak (that is what the old timers around here call them) and some call them water oak.
The official name is Chestnut Oak though.
I own around 230 acres of timberland here in Middle TN and the Chestnut oak is the dominanate species # wise in the population of Oaks. We do have lots of White Oak, Red Oak and a few other misc type Oaks (Post, Black, etc) but of all of the oak trees on my property about 1/3 or possibly a little more are Chestnut oaks.
They are a decent timber tree and usually grade out as white oaks but in the #2 quality.
They have huge acorns, nearly 2x larger than white or red oak acorns.
When a whitetail deer crunches down on one you can hear it pop for about 100 yards.
