-<location_description><i>In</i> Stogerweg - you literally step over it while walking along the path.</p><p>Originally numbered '88' in a fit of optimism while the explorer was getting changed to investigate this impressively draughting hole, it proved in fact to be only 1.2 metres deep and too tight. It appears to be above the inlet below pitch 1 in cave 87, and has been officially renumbered 87b (the painted "88" had faded to near-illegibility by 2018), since the Austrians have allocated number 88 to L&auml;rchenh&ouml;hle. </location_description>
