Muir Wall | A4 Big Wall at El Capitan


The first El Cap. route climb done in one push from the ground by a 2 man team. Named after John Muir, Scottish-American naturalist, environmental activist and co-founder of the Sierra Club.

Two free versions, preMuir and The Shaft, both have some variations from the original aid in line.
