Currently no
information can be found about Thompson's Level. Even NPHT has no plan or
history about it. It is blocked by a fall some 25m in which looks like it may
be debris from a rise above.
NPHT are planning on digging this level,
with a hopeful start in Easter 2008. It is intended to be part of their
Underground Group's first activity. (Last Update 15/01/08).
