On the South Island of New Zealand, on the road from Invercargill to TeAnu near a village called Clifton where there is a cave. Whilst my son and granddaughters explored the cave I marvelled at the the hills above.
Sheep grazing across the faces of steep hillsides sculpt them with countless tracks. This hill was so steep the tracks were like little terraces growing grass so green. The vertical spaces between almost bald or with grass nibbled close to the ground. The tracks emphasise the contours of the hill, a bit like ripples across the face of a wave.
