On the back og the card: Mt Ruapehu (2779m) erupting in September 1995 just at sunset, viewed from the National Park township.
"Mount Ruapehu is an active stratovolcano at the southern end of the Taupo Volcanic Zone in New Zealand. Ruapehu is one of the world's most active volcanoes and the largest active volcano in New Zealand.
Mt. Ruapehu served as the setting for Mt. Doom in the The Lord of the Rings film trilogy. It is predominately featured in The Return of the King as Frodo and Sam stumble up—and then get stuck coming down—its slopes." - in: wikipedia
