Just got back from a week in Tuolumne Meadows with my wife. We didn't spend any time on Half Dome because the route to the Valley was closed due to a fire, but spent a lot of time on the domes in the Meadows. Some of those climbing route walk-offs from the tops of the domes are, as Luke Galyan likes to say, "attention-getters". What's fun and exciting under dry conditions would be a whole different matter after a cold rain shower and dusting of snow. That girl who fell from the chained route down Half Dome probably didn't realize what she was getting herself into, just like probably more than 90% of those coming down the Dome in those conditions that day. With their gear along, the Brazilian climbers were probably the only ones who had any fun.
