Persistence of Nature -- #3




This morning I took four views of the same valiant goldenrod.
Dark area is not shadow but recent road patching.

That's more than persistence - that's pure tenacity.

Reminds me of the trees I see growing from the craggy rockfaces along side the road. It amazes me how they hang on to their tenuous perches with barely any dirt to sink their roots into, yet withstand heavy snow and ice to survive another year.

There's one tree in particular down the road from me that always catches my eye, it sits upon a big boulder with it's roots snaking across the rock, I'll get a picture of it later. It always impresses me as a testament to Nature's persistence.

Trees and plants are part of the cycle of breaking down rocks by getting their roots in the cracks and crevices. The roots apply pressure that trys to spread the walls of the crack. They work in the spring and summer just as water that freezes in the cracks and crevices spreads them in the winter. Eventually you get fine enough grains to start mixing with organic materials to make dirt.
