Although originally untitled, this work has become known as Ben Nevis Hitch-Hike. In April 1967, Richard Long walked and hitch-hiked from London to the summit of Ben Nevis and back. The journey took six days, and at 11am each day he took two photographs. For one photograph he pointed the camera straight up, and for the other he pointed it straight down. The photographs which appear in the work are the only ones taken on the journey.
Long set out at 11am on a Sunday and reached the summit of Ben Nevis at around mid-day on the Tuesday.
