Tikutsika pafupifupi 60 m, timapeza mtsinje womwe umapanga mathithi osangalatsa pansi panthaka, ndikupangitsa kubangula kwakukulu. Pambuyo pa maola khumi ndi awiri akuchita masewera olimbitsa thupi, tinazindikira kuti tadutsa njira yolakwika; ndiye kuti, tinali m'modzi mwa mafoloko ambiri m'gawo lino. Kenako tidangoyima kwakanthawi ndikudya. Tsiku lomwelo tidatsika mpaka kuya mamita 750. Tinabwerera kumtunda nthawi ya 11:00 a.m. Lolemba, ndipo dzuwa likuwala tinafika kumsasa.
Lachisanu nthawi ya 10 koloko usiku, ine ndi Maciek Adamski, Tomasz Gasdja tinabwerera kuphanga.

Gawo ili la phanga ndilovuta kwambiri ndi mitsinje ndi njira zopita ndi madzi ndi mitsinje yomwe imapanga magwero apansi.
Pakati poyesa kupeza njira yoyenera yopita ku siphon yomaliza, tinayenera kudutsa phompho titatsamira misana yathu mbali imodzi ya khoma, ndi mbali inayo, titatsamira mapazi onsewo, tili pachiwopsezo choterera chifukwa cha chinyezi cha makomawo. Kuphatikiza apo, tinali ndi maola angapo pakukula, kotero minofu yathu sinayankhe chimodzimodzi chifukwa chotopa. Tinalibe njira ina, popeza tidali ndi zingwe kuti titsimikizire panthawiyo.
