In reply to Mr. Lee:
Well, Supertopo says of the West Face:
"Is it a "true" El Cap big wall route? It's definitely more of a wall than the East Buttress, but not nearly in the league as other El Cap routes. That said, who cares!? "
Then they say some other things.
Yosemitebigwall.com has a first free ascent list for El Capitan with the West Face being the earliest listed (1979). The next is the Salathe in June 1988 by Piana/Skinner. It was another 5 years for Lynn Hill on the Nose and another 5 again for the Huber brothers on El Nino and Freerider.
Back to Supertopo on the East Butress: "The first ascensionists, in fact, never regarded their line as “climbing El Cap, knowing that the real challenge began just a few yards left of their route.” The first ascensionists were Allen Steck, Wili Siri, Dick Long & Willi Unsoeld in June 1953.
In summary, Radio 4 will likely be happy to be left in peace.
