A track winding back
The geology underlying our farm at Homerton is quite interesting. We have limestone under the sandy loam topsoil, a pretty strong clue to the fact that this area was under the sea in recent geological history. And we have sink holes all over the property, areas that have subsided when a limestone cave underneath collapses. Swamps and drainage lines on the surface follow a linear direction to the south-east, resulting in 'waves' in places. You can see this in the photo of a lane that runs alongside our property. When I was five I had to ride my bike to school on a road like this. It has since been levelled and sealed, and the one-teacher school has closed. That's progress I suppose.
