Second rock slide hits Yosemite's El Capitan in two days

A massive new rock fall has hit Yosemite National Park, cracking with a thundering roar off the El Capitan rock formation, injuring one person and sending huge plumes of white dust surging through the valley floor below.

The slide came a day after a giant slab of granite plunged from the same formation, killing a British man on a hiking and climbing visit and injuring his partner.
