Photo from The Yosemiter
Ok, this really is a coincidence. I posted a couple of pictures recalling the Happy Isles rockfall of 1996, and this happens today in Yosemite Valley. A rock fall from the Royal Arches slightly damaged some parked cars, and forced the closure of the Ahwahnee Hotel until Friday so the chances of more activity can be evaluated. Boulders were the size of "microwave ovens".
Thanks to Loyd Schutte and the Yosemite Blog and the Yosemiter for up-to-date info. Thanks to Loyd for the morning photo link!
Update (8/27): links to pictures of the new rockslide on the Yosemite Blog here and here, and on Yosemite Trekker here (thanks, Loyd)
