The cliffs along the Pohangina river are formed from soft mudstone — millennia of sediment turning to rock but not quite there yet. Meanwhile, the river wears it down. Most of the riverbed, on the other hand, comprises hard, metamorphic boulders and gravel, tumbled down from the Ruahine range. The power and complexity of geological processes never fails to astonish me.

They remind me of cloud formations. Well, in this photograph at least.
I think I'd like to just sit. There.
This is just stunning. I get such a sense of movement from these ROCKS. The ones in a tumble in the water look like some sort of beings coming to the surface, and the cliff face still seems to be shifting. Love your black and white work!
Liminal eons, for rocks.
Leonie, it's a great place to sit. Need the sandfly repellent, though.
Barbara — thanks! :^)
Zhoen, change is constant.
Brings to mind a verse from Tennyson's "In Memoriam":
"The hills are shadows, and they flow
From form to form, and nothing stands;
They melt like mist, the solid lands,
Like clouds they shape themselves and go."
A very apt quotation, Avus. Thanks!
