Stem Flow
We’ve had on and off rain recently.
Chemicals from the pine bark form a white flux when it rains.
It only flows from near the base of our only pine tree,
and can easily be seen from a distance.
The foam gradually slides down the bark of the pine tree and evaporates on the way down.
It will dry rather quickly after the rain stops, and the sun comes out.

Thanks for an interesting set of pictures documenting something that I have never seen.
