Unusual Trees in the Woods

I saw a 2 meter tall native holly, just north of the SW Cutoff Trail, only the second of this species I have seen in the Woods. I also saw again a young sycamore maybe 10-20 years old in the wash-out small stream channels south east of the Elm Bridge.
And I pondered the triple split trees (still living and with cotton rat nest at base) west of Hackberry Alley. Mulberry.. red hearted xylem, small vertical lenticels.
The water in the East Wash had cleared up substantially today. There is a thin new solid coating of red clay all along the Wash.
