All the Castle community mourns Felix's death in Yosemite on the 2nd of June 2013. Felix, 28, was a regular climber at The Castle and worked for a brief time in the shop (when it was run by Urban Rock). He was climbing East Buttress on El Capitan when he was hit and killed instantly by rock fall.

A lovely article about Felix was written by his friends, Luke Alvarez and Tom Brooke, and published on UKClimbing. There is also a Facebook memorial page.
