In 1968 the topographical survey map shown above was the only available source  for navigating the canyon.

As you can see it contained very little useful information about trekking or conditions.

ABOVE: A nostalgic map created after the Expedition for members of the team as a reminder of their time in the canyon. Illustrated by Tony Beckley

BELOW: This rough hand drawn map recording the expeditions daily progress was drawn and annotated by Tony Beckley and Terry Davidson in the canyon at the time.

By transcribing the 1968 plotting points and annotations onto a current satellite map it was possible to recreate a fairly accurate pictorial reference and history of the expeditions progress through the canyon.
