Your “vision” adds greatly to the gravity-bound mechanical processes of weathering whereby boulder turns to pebble turns to sand in a downward trickle, a melt whose slow turbulence does offer many great shapes. Chemical weathering might suggest a model which has assonance with yours, but I cannot imagine it. Perhaps limestones evanesce into the atmosphere, but I do not think acidic stones do. Certainly the chemistry is most profound. Increasing limestone exposure moist skies is like increase the rate of combustion in an wood stove by letting in more air. And an oxidation/combustion allegory is always fun, being one in which things burn as they oxidize!

The magic you add is spatial, of memory, formal and recognition based. Boulders, hillsides, loose their volumes and their looks to the air which continually displaces them. Shapes are nibbled by the air, occupancy of space is temporary. As I mentioned, so often mountain and hillside salience is associated with uplift. With uplift, instead of the sky retaking its space, there is constant exchange of territory, back and forth. Perhaps this liminal surface pulses like sand on a beach. Perhaps rocks simply can’t stand the loss of pressure up on the surface, and they perish like whales on a beach. There is nothing to hold a stone together once air encroaches on five sides, the sixth side being downward facing and the stone’s only fading memory of its kindred lithosphere. I wonder if my newly sharpened study will increase the rate of erosion? Thank you for the insight into our unravelling and replenishing hills!

And sorry for any tedious redundancies! I will cast and recast this new model indefinitely and in many pourings! I have to run outside now and see if the hills have moved any; I know I’ll be able to spot it.
