False 1623-225 Jahrzehnschacht 1623 2c 1/S + 225 90 ADAM 1623-225 CUCC 1990 (by Adam Cooper on 12/7/1990) The obvious pit by the "high level" route to 161 was descended using IRT (indestructible rope technique) after declining to use a Bunda belay. Ended at about -12m (choked as usual) with a ledge about halfway down. <20m rope presumably. caves-1623/225/225.svx 1623/225/225.html
