A man and a woman were rescued after they were stranded on a cliff about 1,000 feet above Eaton Canyon Monday morning.

An Altadena Mountain Rescue team began the search at 8 p.m. Sunday in the canyon near the 2200 block of Pinecrest Drive. The hikers were spotted on the cliff at about 11 p.m.

They did not appear to have suffered any injuries after a cool overnight that included a rainstorm in Southern California. Authorities waited for a break in the weather before launching a rescue helicopter for the airlift operation.

Eaton Canyon, located at the base of the San Gabriel Mountains north of Los Angeles, has been the site of several rescues in recent years. The County of Los Angeles has issued an alert for hikers to avoid the undeveloped trails that lead to the top of Eaton Falls.

The hiker were off the trail in the falls area when they were stranded, according to authorities.

"It's life-threatening," said hiker Ronald Derayunan. "Especially, in conditions like this, it's really slippery. I'm glad they closed it. It's not for everybody."

Some hikers who attempted to reach the falls have been seriously injured. In March 2013, a 17-year-old girl died after falling from a cliff during a spring break hike in the canyon.
