VIDEO: A woman's hike didn't end the way she wanted it to and had to call emergency crews for help when she injured her ankle on Thursday night in Phoenix. Nick Arapkiles, who was also on the mountain, said the woman slipped, rolled her ankle and fell off the path around 7:30 p.m. on the Cholla Trail side of Camelback Mountain. She was about 3/4 of the way up. A boulder then rolled over her ankle. Arapkiles said the boulder was about the size of a melon. Technical teams made their way up the mountain and found the 22-year-old woman in stable condition, firefighters said. "I mean we stayed up there until firefighters got up there," Arapkiles said. "There's (sic) probably 20 of them up there."
