Yesterday I visited my spot nestled within centennial woods, I ventured towards the large ash tree that marks the central point and sat down, as I observed the sights and sounds around me I noticed several that stood out. They were the sound rustling of the leaves, as the wind propelled them through the woods, the sight of birds and squirrels in the leafless trees, and the smell of wood wet with the recent rain. In my map, you can see the center point marked by the large ash tree, surrounded by the smaller trees of many species, beneath them are the fallen logs, as well as the rocks.
As far as changes I noticed essentially all the leaves have now fallen, and the understory is covered in dried leaves of many types, however, most other vegetation has remained the same, and the only noticeable changes were a slight darkening in color. Something I noticed on this visit that I previously had not was the number of mushrooms present, both on the ground and on logs/trees.
