To the west, a short walk reaches a 3m climb to a higher level, choking rapidly. Thought by the Austrians to be one of a group of shafts numbered 36 in the Kataster, but the location of B1 relative to B4, which is very near 36, precludes this interpretation. Unfortunately, B1 was not relocated in a search in 1990. 14m 1623/b1.htm
