Pete Lancaster surface surveying on the SE slopes of the Vorderer Schwarzmooskogel in 1983, above the Stellerweghöhle system.

This was the first attempt to find surface entrances corresponding to the large phreatic level of the 'Dartford Tunnel' area in 115, and specifically to find the surface location of the very string outward draft at the end of the Fuitility Series (Nutzlos) found by Chas and Phil Sargent. Phil had another look for these hoped-for entrances in 2018 and 2019, and learned that GPS altitudes are too poor to be useful. We need to do more surface suyveying like this!
