My grandparents took my Dad & Uncle through the Great Smoky Mountains National Park in the mid-1960s. This is a picture they took that looks like it was near Fontana Lake.
At the time, the park was 30 years old. It’s interesting to see pictures like this that show successional forest coming up where there was once heavy logging.
All these areas are now 70+ years since the park founding with a much more developed forest.
You can barely tell that the forest around Lake Fontana was heavily logged before the park.
