In between updating the AM Handbook, Chris Scott covers the remoter corners of Australia for Rough Guides - and the gorges of the Hamersley Ranges in northwestern Australia are the setting for his latest film.

Staying behind the camera this time, Chris follows Jeff aboard his ratty ex-African HPN Boxer, and Bob and Danielle - halfway through an RTW honeymoon on their fully-kitted R1150GS.

When flooded tracks nearly drown the 1150, Bob and Jeff continue on the HPN. Then that too is left behind as the duo undertake a thrilling and irreversible descent into the freezing gorges of Karajini where Jeff and Bob find themselves inside a rarely seen wonderland of shoulder-wide chasms, hidden waterfalls and flooded canyons bounded by towering red cliffs.
