Trees growing on top of rocks (12)
|I was curious about a question Musa asked on one of his posts. Do rocks really store moisture? |
I found these two trees growing on top of a large rock outcropping while visiting Cooks Forest in Pennsylvania. It was obvious to me that the large tree (at least thirty foot high) started to grow on top of the huge boulder many years ago. It has since dropped roots into the soil below where it now thrives.
I checked out a site on the web to see why plants seem to grow out of rock crevices, this is what I found.
I will post a closer view in a WS
