standing block stability
John,
You are right, and this mechanism for instability had already begun
to dawn on me. In other words the stone would rotate over on a
hemispherical ball of dirt stuck to the bottom. Mind, the meadow
barely has any soil at that point, just a thin layer of clay and
broken shale 8-10 inches over fractured bedrock, but it would still
be unstable. Making a huge buried concrete base as suggested is a lot
of extra work and expense, especially for a temporary site. I can get
blocks of lower aspect ratio and it might be more sensible to just
work with one of those. The question then is, at what aspect ratio is
a block stable; 3.5, 3, 2.5, 2 ...?
