RE: August 31 2021 _ Heysen Trail Day 2

I know! Imagine the hours that went into building those walls! Supplies were hard to come by for the early settlers in the region and most of them were pastoralists. Keeping sheep and cattle rather than cropping. I'm speculating, but I assume they built these walls to keep the livestock in. The wire fences would have went up much later. You'd have to be tough to survive back in those days!
