Waimangu
This sequence was shot on a visit to Waimangu Geyser, which is specifically mentioned in the voice-over, as well as in Ross’s travel book Haha Whenua - das Land, das ich gesucht (1933). This places the shooting of the sequence likely in June 1929: Shipping information indicates that Ross was in New Zealand from April 28 to June 21, 1929, crossing the country from Bluff to Auckland.
