I heard this afternoon that Moonlight Buttress in Zion had been free-soloed by Alex Honnold. Very impressive and very dangerous. 13a and much 12 on friable sandstone. No doubt Climbing will have more on this very soon.
My piece about climbing past 40 is up at FRB. You can find it here.
(I want to add that the source for the Moonlight Buttress story is very reliable but it is still unconfirmed by other sources.
For a topo of this incredible route go here.)
