A massive new rock fall hit Yosemite National Park on Thursday, 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.

A massive new rock fall hit Yosemite National Park on Thursday, 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 wife.
One person was injured and was flown to a hospital, park ranger and spokesman Scott Gediman said. There was no immediate word on the person's condition.
The park indicated that seven rock falls occurred during a four-hour period Wednesday on the southeast face of El Capitan. However, it was rare for such a collapse to kill anyone, longtime climbers said Thursday.
The last time a climber was killed by a rock falling at Yosemite was in 2013, when a Montana climber fell after a rock dislodged and sliced his climbing rope. It was preceded by a 1999 rock fall that crushed a climber from Colorado. Park officials say rock falls overall have killed 16 people since 1857 and injured more than 100.
Foster and his wife were not on the cliff, however. They were hiking at the bottom of El Capitan far from trails used by most Yosemite visitors in preparation for an ascent when the chunk of granite about 12 stories tall broke free and plunged, Gediman said.
Yosemite geologist Greg Stock said the break was probably caused by the expansion and contraction of the monolith's granite as it heats up during the summer and gets cold and more brittle in the winter.
Climber Ryan Sheridan had just reached the top of El Capitan, a 7,569-foot (2,307-meter) formation, when the rock let loose below him Thursday.
"There was so much smoke and debris," he said by cellphone. "It filled the entire valley with smoke."
"It was in the same location of the previous rock fall. A larger rock fall let loose, easily three times the size," Sheridan said.

One person was injured and was flown to a hospital, park ranger and spokesman Scott Gediman said. There was no immediate word on the person's condition.
Meanwhile, the man killed Wednesday was identified as Andrew Foster, 32, of Wales. The park didn't identify his wife but said she remained hospitalized.

Rocks at the world-renowned park's climbing routes break loose and crash down about 80 times a year. The elite climbers who flock to the park using ropes and their fingertips to defy death as they scale sheer cliff faces know the risk but also know it's rare to get hit and killed by the rocks.
"It's a lot like a lightning strike," said Alex Honnold, who made history June 3 for being the first to climb El Capitan alone and without ropes. "Sometimes geology just happens."

The rock falls came during the peak of the climbing season for El Capitan, with climbers from around the world trying their skill against the sheer cliff faces. At least 30 climbers were on the formation when a section gave way Wednesday.

Foster and his wife were not on the cliff, however. They were hiking at the bottom of El Capitan far from trails used by most Yosemite visitors in preparation for an ascent when the chunk of granite about 12 stories tall broke free and plunged, Gediman said.
The slab was about 130 feet (40 meters) tall and 65 feet (19 meters) wide and fell from the popular "Waterfall Route" on the East Buttress of El Capitan, Gediman said.

Yosemite geologist Greg Stock said the break was probably caused by the expansion and contraction of the monolith's granite as it heats up during the summer and gets cold and more brittle in the winter.
Officials had no immediate estimate for how much the big rock weighed. But Gediman said all of the rock falls combined on Wednesday weighed 1,300 tons (1,100 metric tons).
