47° 40' 41" N 13° 48' 58" E From Top Camp, climb the "high" route towards 161. Just past the highest point, join a traverse round the Schwarzmooskogel heading south and eventually more west. If you pick the right level, this passes the large open shaft of 140. Alternatively, the cave may be approached from the summit (point 1843) though various cliffs make this approach difficult. P?
