The only bit of ice I could find -- it took me 36 hours of skiing around trying to find an airstrip -- was exactly 473 meters. I could measure it with my skis.
Singura bucată de gheaţă pe care am putut să o găsesc - mi-a luat 36 de ore de schiat până am găsit-o - măsura exact 473 de metri. Am măsurat-o cu schiurile.
