The Montana megaliths are typical of rock-block
landscapes consisting of closely spaced residual
blocks of rocks separated by narrow intersecting
corridors. This type of residual landscape is
variously termed as either "rock cities" or
"ruiniform relief." Isolated stacks of such
residual blocks, which surrounded by rounded
hillslopes are known as "tors." The blocks are
the result the weathering and erosion of igneous.
metamorphic, or sedimentary rocks along
rectilinear joints of various spacing.

A discussion of the formation these landforms is in:

I have access to the above paper.
