The RAHA stone was first depicted by M.
Much in 1879-1880 and provided with an
interpretation that is no longer tenable
(Raha in the sense of border). Miners
found the stone when they were setting a
survey point.
If you look at the signs closely, you can
see an R on the left, below which there
is a G that Much omitted. Then there is
a tunnel symbol, below which there is an
X or actually a diagonally lying cross (as
a marking symbol). To the right of the
tunnel symbol, there are an H and an A,
with the A looking quite different from the
tunnel symbol.
Prof. Lippert interprets the inscription as
follows: HA" for Hallein (representing
timber rights here for salt production)
and "RG" (RG either as an individual or
a group of people) share timber rights
(?) for extraction from the stone - in this
case, probably for extracting spathic iron
ore. Copper ore is no longer present in
these rock units, but evidence of ankerite
extraction is found.
