Peering down at the mighty Waimakariri

Quick cartoon of the main dividing range and Waimak river. The lions demonstrators that organised a weekend-long field trip to the Arthur's Pass area; Simone Hicks and Dr. R. Ewan Fordyce, one of the country's best known geologists/paleontologists and local film celebrity (lol).
Simone: You want to go all the way down there, to look for trace fossils?? You're mad!!
Ewan: We're all mad here...
