A 19-year-old Billings woman who fell off the Rimrocks was identified Wednesday as Ivy Bird.
Bird is being treated at St. Vincent Healthcare, where she was listed in serious condition.
Bird fell an estimated 100 feet from the Rims early Tuesday, suffering numerous broken bones and other injuries, police said. The incident happened just before 2 a.m. near the 1900 block of 11th Avenue North.
Police said Bird was with two friends and may have been drinking alcohol when she slipped over the edge. A fire rescue crew rappelled down to the woman and lifted her to the top at about 4 a.m.
