Surface survey and Prospecting below 115.
Pete Lancaster
The aim was to find the end of the Futility Series popping out of the hillside below 115. We surface surveyed down to a permanent station, marked with bolt hole and lots of red paint: P1983/1. This was almost directly below 115 and on the edge of the big trees. It was at E77.2, N-237.3, H -195.8, whereas the end of the Futility Series was at G30: E 139.7, N -54.2, H-187.8. So we were (!) at the right place, but the cave end was 180m into the hillside. We had a good look round but didn't find any signs of caves there.
So we looked at a big phreatic entrance further east (up the valley) and ~50m higher. This was looked at in 1982, but a bit of proddling released lots of boulders + we were able to follow up a narrowing bedding plane at ~60°, for 10m until it got too loose/small. Very difficult descent on scree to the end of the Altausseer See + then the Schniderwirt for Weizen Bier.
