YOSEMITE (CBS SF) – When word broke earlier this week that the rock face of Half Dome in Yosemite National Park had lost a big chunk from a popular climbing route, it wasn’t immediately clear to the average visitor what the difference was. Now park officials are making the results of the facial peel quite clear.

On Wednesday afternoon, park officials released the following images detailing the roughly 100 by 200 foot scar.

Park geologist and climber Greg Stock said Tuesday that officials are now determining how the new route changes the climb.

Nobody was injured or witnessed the fall believed to have happened one night last week.

Stock says the relatively thin sheet of rock simply peeled off.

He says there are several other routes for climbers going up the 1,000-foot sheer face.

Stock says rock falls are common, but the size of this piece is impressive.

Via Facebook, Yosemite also posted a video showing what it looks like when rock crumbles to the Yosemite Valley floor.

Stock says this doesn’t change the path for hikers taking a cable route to the top of Half Dome.
