Last week the GMH centreline work was completed and checked in, and the therionising progressed a bit and we eventually (with a lot of
email) got to the bottom of the 'is Shagged Spit/GutenMorgenHoehle the same cave' mystery. Thanks to all who contributed - it was hard work, but we got there.
(The answer is no, there are two entrances, originally believed to be the same cave, the upper (tagged, explored, described, unsurveyed, unlocated, unphotoed) one is SS and the lower (explored, surveyed, photoed, undescribed, located) one is GMH).
