Thirty-year-old Anita Mann was trapped between two buildings here in Portland, Oregon for more than four hours before firefighters were able to rescue her on Wednesday.
It is unclear how she fell into the tight space between the two walls.
A passerby heard her screams and called for help.
Firefighters had to cut two holes in the cement wall of a parking garage and used a soap-like substance to free her.

"That last couple feet, she had that look of determination and I think we were all pretty convinced no matter what, she was coming out that way."
Mann was taken to hospital for evaluation.
