Well pulled the pavers up and found that there were channels running under the edging and dropped into what was apparently part of a garbage dump area.
Found no big hole but a foot under the sod , in good soil, the shove hit soft spot and clinked.
I pulled up broken glass, metal shards, a tiny , and I mean tiny, bottle and a old zinc canning jar lid.
Put the dirt in the hole an packed it then put the lump of sod back down after which I filled the main channel, only two by two with polymeric sand.
Did not get the pavers totally put back in but laying them on polymeric sand meant the ones put down did not move though unused exposed P sand was useless and I pulled it out.
As usual, and I knew this would happen before I started, I pulled the pavers and did not check the pattern or exactly where and how some I cut and ground, the unseen bottom, to fit special places were located , SO, now it is two-thirds redone and the new ones are at a different level, and the edge is pinching on one side. (The latter is odd as the pavers were not narrowed or shortened so they should just fit regardless.)
I can assume that I had spaced them generously so I did not have cut them so now being spaced in the normal manner I have extra space.
Oh, well , It needed raising any way so, now it is.
