This sequence of photographs was taken in May/June 1968 and encompasses several runs of the Cliff and Chasm course.
The Cliff and Chasm course consists of two parallel steep-sided ridges. The aim of the course is to convey a barrel filled with concrete up one side of a ridge, rig up some apparatus to transport it across a chasm to the opposite ridge then convey it from there, together with the tranportation tackle, down that ridge then return to base.
The mission starts within Royal Arthur where a two-wheeled cart is loaded up with a spar, a pulley, some rope and a wooden barrel full of concrete. The team transports the cart and its contents out of Royal Arthur and along the road to the base of the first cliff. From there the contents of cart are unloaded and transported up the side of the cliff to its peak. The spar, pulley and ropes are assembled to facilitate the transfer of the barrel across the chasm to the opposite ridge. On completion of the transfer, the rig is dismantled then dragged through the chasm to follow the path of the barrel down to the base of the cliff. Finally, the cart is reloaded with the tackle after which it is then one mad rush through the lane to return to Royal Arthur in what was hoped would be a record time.
If you like what you see in these images from fifty odd years ago then a small donation to the Castle Cary Museum would be much appreciated.
