Two climbers have died after falling from Yosemite National Park's El Capitan, park officials said Saturday.

Park rangers received multiple 911 calls at 8:15 a.m. reporting that two climbers had fallen while climbing the Freeblast Route on El Capitan. They responded to the scene and confirmed that the climbers had fallen and did not survive the fall.

Park officials identified the two climbers as Jason Wells, 46, of Boulder, Colorado and Tim Klein, 42, from Palmdale, California.

"We don't know exactly what caused this incident. That is all still under investigation," said Yosemite National Park spokeswoman Jamie Richards.
