American Basswood(Tilia americana) is a common tree on my place. It attains a large size as this pic proves:
When I came close to this tree to measure it, I saw a lot of rot inside the huge trunk, the whole inside is hollowing out. The circumference of the trunk is around 16 feet. I really don’t feel comfortable that close to this basswood tree, as if a sneeze of mine could make it come tumbling down.
