You can see the eroded the cement pillar, 2nd from the end wall, better view of it in the vid. Month ago I propped a sheet of pws against pillar & shovel a lot of dirt in behind, not all of it stuck though. Those cement pillars go down 12 feet, so no worries of it moving.
The orange string you see (baler twine), once I get the bottom dug out, set the string in place so I have something to eyeball as I cut the ramp to a more favorable grade, about 12 degrees.
