I have friends who live on a mountianous 'rock farm'
I taught them the following uses of rocks;
- on contour rock ledges in an olive grove on a hill to capture silt and moisture for the
trees.
- dry stone walling for a set of walls at their gateway.
- I built a pair of loveseats at the hill top for the two of them.
- reinforcing the drive edge as it goes around a dam.
- erosion control in a manmade
water channel to prevent erosion.
There are many rocks left, so I keep thinking of good uses for them.
