The video includes a young woman on a day hike in Eaton Canyon who found herself clutching the side of a cliff.
Authorities warn not to believe the information being spread through social media about a "so-called safe hike to a second waterfall around Eaton Canyon.''
There is no developed trail leading up to the top of Eaton Falls, according to a news release by the Los Angeles Sheriff's Department. It is a rugged natural area in the Angeles National Forest. People have died or become seriously injured by climbing, in an attempt to continue farther up the canyon.
