Bernie and I return to our transporter and travel back along three miles [5 km] of bumpy tunnels before stopping at a large cavern. A vertical shaft, about 30 feet [10 m] in diameter, connects this cavern to the surface.
Mēs ar Bērniju atgriežamies pie savas mašīnas un braucam piecus kilometrus atpakaļ pa nelīdzeniem tuneļiem, līdz nokļūstam lielā telpā, ko ar virszemi savieno vertikāla šahta, kuras diametrs ir aptuveni 10 metri.
