This is the view loking south at the north access slope to the dig site. For years this has clearly been the access point for most people to the area that I am now digging. During and after the rain this slope because of the slippery clay makeup of the soil is virtually impassable. Though only 3 feet from base to crest when moistened it posed a serious barrier. From this view,about middle center is visible presently the highest point of the interior wall I have constructed.From base to crest the wall is approximately 5 feet with about a girth of five feet. As of Tuesday 4 12 2011, I began digging into the access slope cutting into the incline at a vertical and implying a wall at it base by piling the dirt in its path.
