Within a slope constructed at the angle of gravity, that’s to say at the angle that is the balance between the earth’s spin and the concentration of that spin at it’s core, water flows downhill at a rate balanced to the evaporative potential of the air above it, and the plants (in this case bunchgrass) that represent it (and mine it). When these lines of energy are cut, such as by the Grey Canal (now a walking path) in the centre of the image below, the balance is changed, water pools, and wetland life colonizes it. The seeds drifting on the wind that created the cat tails below are blowing everywhere through the valley. They materialize as a new wetland only when there is a wetland to materialize in, which is dependent on alterations to the balance of pressures between the atmosphere and gravity. The Earth is a child of the stars, and we can harvest their energy, should we watch and pay attention. Soil is the story of this balance. So is life.
Tomorrow: the beauty of surfaces within the story of soil.
