Martin Crook on Pump Station Zebra 7A+/B photo: Crook collection

Martin Crook has completed an epic power endurance traverse line at Tan y Grisiau. Pump Station Zebra 7A+/B is located 5 minutes further up the dam road past the Hippocampus block, but set back behind a stone wall, which is itself about 100m from the road.

The traverse runs, from the obvious sitting start position, left-to-right across the zebra-striped striations on the steep wall. A range of pinches, crimps and slopers lead to the pressure drop crux move and a physical span to big boss at base of groove. The last half is a posing lap on slabby rock.

An alternative low version of a similar standard comes nicely into the drop move. NB. It needs four dry days to come into condition as the groove at the end of the steep section seeps.

Check out the link below for a great little interview Martin did with Trek and Mountain magazine; it includes footage of Pump Station Zebra:
