Search and rescue teams have responded to 14 rescues on the 10,068-foot peak and the surrounding area in the past month, officials said Tuesday.

Earlier this month, a female hiker died after sliding an estimated 500 to 700 feet down Baldy Bowl’s steep, icy hillside Sunday, authorities said.

“Please know the current conditions on Mt Baldy are adverse and extremely dangerous,” officials said in a news release.

There's a long, narrow ridge along that hike called "The Devil's Backbone", with very steep slopes on either side. It's safe to walk in summer, but when there's snow and ice, like there has been recently, it's extremely dangerous, especially for people who are inexperienced at ice hiking and improperly equipped.
