Pete Lancaster at the final sump in 1623/115, Schnellzughöhle during the explorations of 1982. This was the second of only two trips (both camping underground) to reach this point: 885m (1999 survey figures) below the original Stellerweghöhle entrance (and at -974m from the highest entrance, linked in 1985). The trip was a 32 hour marathon of surveying, the odd bit of photography, and derigging the lower streamway.
