And a bit closer...

This is WHY BONSAI.
Also part of why piñions are my favorite tree.
One tiny seed found it's way into a tiny hole in a 30 ft/10m sandstone cliff wall, and with a bit of luck will in some years become something we would all envy in our pots.
Not the first time I've come across something so amazing and fascinating, but this time I had a camera and some people to share with.
