NEW CASTLE, Colo. (KKCO) -- Elaine Hill recently had hand and arm surgery but decided to go for a walk to keep active during the recovery process.

She was unfamiliar with the trail, but said she had no idea her evening would end the way it did.

"Normally it was getting toward evening so no one is going to be in that part of the wilderness, but I didn't know it was the wilderness when I walked on the path," said New Castle resident Elaine Hill.

Hill says she slipped on some gravel and the next thing she remembers, two girls were talking to her.

"She was unconscious and everything, and we were like, 'Can you hear us?' but she didn't answer," said Coal Ridge senior Grace VanDevende. "Kayla kept talking to her, and I decided to call 911."

VanDevender and Kayla Warren said they had never been in a situation like this before. The girls said it was a life-changing experience.

Hill said the girls saved her life and refers to them as her little angels.

"Every time I think about it, it's hard to believe that it happened this way," said Hill.

A unique bond was created from this chance meeting.

"Gonna be friends forever," said Kayla Warren.

Hill's doctors say that if the girls had not been there, she may not have made it through the night due to the severity of her concussion.
