An entrance apparently previously explored (marked "-"), surveyed
to in 1999 and given the temporary name MI5. It is a small shaft, being
pointed out by Mike and Tina Richardson, at the end of a short surface
survey from 161c. This view is pretty much on the route from the col
between Vorderer Schwarzmooskogel (seen in the background) and the
south ridge of Hinterer Schwarzmooskogel leading to the 161a entrance.
