A Deschutes County search and rescue team accompanied an Idaho woman down South Sister Friday evening after receiving a report that she had suffered a potentially serious medical condition.

Shortly after 5 p.m., a fellow hiker called 911 to request help for 37-year-old Melissa Perez, of Twin Falls, who had become ill after summiting South Sister. At the time, Perez was about one mile north of Moraine Lake on the South Sister climber’s trail. She was among a group of more than a dozen Idaho hikers.

A Life Flight aircraft took off at 5:37 p.m., according to a Deschutes County Sheriff’s Office press release, but turned around about 20 minutes later when Perez told a search and rescue deputy she had begun to feel better.

Search and rescue personnel made contact with Perez shortly after 7 p.m. and determined she was well enough to continue the hike down the mountain. She reached the Devil’s Lake trailhead at about 9 p.m. and opted to seek medical attention on her own.
