Search Continues for Missing Hikers : Lost: Teams find no sign of woman and 11-year-old boy beset by high winds and snow on Mt. Baldy.

Searchers continued to scour the summit of Mt. Baldy on Saturday looking for a 37-year-old recreational therapist and an 11-year-old boy who remained lost for a second day after a surprise snowstorm and freakish high winds hit the mountain.

Ten teams of rescuers, totaling about 60 people, searched the mountaintop--sometimes crawling on hands and knees in gusting winds--in hopes of finding the pair who had hiked to the 10,064-foot summit during an annual post-Thanksgiving outing.

The missing pair spent Friday night lost in temperatures that dropped to 13 degrees, with a wind-chill factor of minus 33. Conditions Saturday night were expected to be as cold.

Cynthia Moyneur and Ryan McIntosh were part of a group of Orange County residents--two adults and four young people--who set out Friday afternoon on the two-mile hike from the ski lift at the 8,500-foot-level of Mt. San Antonio, Mt. Baldy’s official name.

Moyneur and her boyfriend, Chris Jordan of Yorba Linda, left the “notch” area of the mountain about 1 p.m. Friday, with two of Jordan’s daughters, his nephew Ryan, and a girl who is a family friend. Moyneur and Jordan had made the hike the previous two years on the day after Thanksgiving.

Scott Adams, the ski lift operator who carried the group up, said he pointed out darkening clouds and warned the group that a storm was imminent. They started out anyway, but the three girls became tired so Jordan led them back down. Moyneur and Ryan continued the hike, which in good weather takes about 90 minutes, according to a San Bernardino County Sheriff’s Department spokesman.

Other hikers saw the pair at the summit, but the lift operator notified authorities when they did not return. The winds came up about 5 p.m., and by 7 p.m. the storm had hit with gusts up to 100 m.p.h., authorities said.

Moyneur, a physical therapist, jogger and avid cyclist described by friends as being very knowledgeable about hypothermia, was wearing calf-length spandex pants, hiking boots and a thin jacket, according to authorities. Ryan was wearing an orange fluorescent jacket, jeans, T-shirt, black sweat shirt and Chicago Bulls hat.

Neither had food nor water with them, authorities said, but Moyneur had two flares and a compass.

Searchers believe that the pair may have become lost coming down from the summit on one of five trails that leave the peak area, said Deputy Ruben Gonzales, a spokesman for the San Bernardino County Sheriff’s Department.

“We’re pretty hopeful with her (Moyneur’s) experience and their dress that we’ll be able to bring them out,” Gonzales said.

But searchers came back Saturday with little to report. “I’ve got to tell you, we didn’t see a sign of anything,” said Jeff Humphries, a member of the San Dimas Mountain Rescue Team.

John McIntosh, Ryan’s father, said he was keeping his confidence high because of the number of search teams out. His son, who plays baseball and football, is considered “athletically adept,” he said. “Ryan is a very wonderful and special boy.”

As the day began to wane, however, the father said he was becoming increasingly nervous.

“As any person that gets caught up in this situation, one wants to be hopeful and optimistic, but on the other hand we want to be realistic,” he said. “We have a range of feelings, from sheer terror . . . to optimism.”
