4 . Leah Brown aged 36 fell several hundred feet from Oregon’s highest mountain right before the eyes of a group of volunteer rescue workers who rushed to her aid and helped save her life.

The woman was coming down a popular path (小路) on Mt. Hood, about 70 miles east of Portland, on Saturday morning, according to the local police. Mt. Hood is the highest in Oregon, standing at around11.240 feet.

The fall was seen by members of Portland Mountain Rescue (PMR), a volunteer organization focused on helping people in mountainous areas. The group called 911 and rushed to the woman, providing medical care. They helped keep the woman warm for seven hours as the police worked to get her off the mountain safely. Finally, the woman was evacuated (转移) to a parking lot at 9:30 pm and taken to a hospital.

The climber, Leah Brown, said she didn’t know what caused her fall. “I can only guess it was either an ice tool or a crampon (冰爪) that didn’t land and stick like it should have, so I became detached from the mountain,” Brown said. “The thing I’d like to most stress is my appreciation for the members of PMR who evacuated me and took good care of me the whole time,” Brown added. “They saved my life. ”

In a statement after the rescue, PMR warned of the dangerous winter conditions at the mountain. “The short days and lower temperatures mean that the snow tends to be very hard and icy, and the conditions tend to be much steeper. Climbing the mountain in icy conditions is much more difficult,” the group said.
