 These roadside boulders were saved from destruction in a 1973 road widening scheme by a six-year protest by local people, climbers, historians, conservationists and geologists.Climbers particularly associated with the area include John Menlove Edwards (in the 1930s and 1940s) and Joe Brown (in the 1950s and 1960s).The British 1953 Mount Everest expedition also trained in the area, and were based at the Pen-y-Gwryd Hotel at the eastern end of the pass.
