Death on Yosemite’s Muir Wall
Already through the three cruxes of the climb and just 600 feet from the top of El Capitan, Mason Robison did what we’ve all done before: pulled on a loose block. The rock fell, cutting Robison’s lead rope and sending him to his death. Chris Van Leuven eulogizes the 38-year-old stone mason, analyzes the accident and teaches us something about Yosemite Valley geology.
