I was thinking about oak trees. There are quite a few around here. They grow very tall. I tried to take a picture of the new leaves on a bottom branch and I wasn’t tall enough. I don’t know how long the oak tree had been standing. but it was older than a decade.
The pictures of old oaks that I found aren’t identified.
