NOTE The shape, length and orientation of the cave is very suspiciously similar to the explored but not surveyed 1623-114 which is very close (60m) to Schnellzughohle and does indeed look like a smaller version of Schnellzughohle. So is the survey location of 1623-228 in Egglgrube valley incorrect ? It uses the nils2000 fixed point *fix 1000

The location of this entrance is just above the edge of the cliff, which is in thick impenetrable pine scrub (failed visit 11th July 2024), whcih is another reason to be suspicious.
