John Sumner (climber)

John (Fritz) Sumner (13 March 1936, in Blackburn – 2004) was the pre-eminent exploratory climber in his chosen domain of Mid Wales, climbing cutting-edge routes on the remote crags and cliff-faces south of southern Snowdonia starting in the mid-1950s.

Sumner dominated climbing in Mid Wales, including routes on the waterfalls of Maesglase.
