Mt Ruapehu

Ruapehu

The sun lowered in the west and the moraine cast a shadow on its eastern flank showing the sinuous ridge ahead of me.  Seeing the moraines on this volcano are relatively easy because there aren’t many trees in the way.  But to the untrained eye, a moraine ridge and lava flow levee may appear the same.  When mapping some of the Last Glacial Maximum (occurred about 20,000 years ago) ice extents, the glacier outlines need some interpretation because a new volcano (Mt. Ngauruhoe or Mt. Doom in Lord of the Rings) formed in the time since glaciers retreated.  It blows my mind that volcanoes can form in such a short amount of time!
