The idea to chip out part of the broken stone seemed plausible. I had forgotten the full nature of these mud stones. They commonly have a core of silvery gray material that is filled with fossils and is incredibly hard. When these mud stones are out in the open this core is impervious to sledge hammer blows. What made me think that I could chip away at it when it was part of the wall? The silvery gray color is hidden under frozen reddish brown mud.
Five new stones have secured the right end of the fault. A shim can be worked under the second stone of the patch. The repair should hold the wall in place. When the supply of wall stones is not frozen under ice and snow we may be able to find stones that will do a better looking job of filling the hole. For now the wall is ready for winter.

I think the irregularity of the smaller stones just adds to its charm. :) Good job in saving the wall!
