Southwest of Abergavenny
I believe that this picture is facing southwest from Abergavenny. It's hard to get an idea of the relief--how steep and how high--the topography was, but some of these mountains and hills were pretty tall. I think that part of the reason they don't look very tall is that there is so much farm land on the mountainsides--but that is because they aren't generally very steep, like the mountains in Utah and Colorado.
