'Experienced Backcountry Hikers' Needed In Search For Missing Man

San Bernardino officials are hoping experienced hikers will help in the so-far fruitless search for a German tourist who went missing Oct. 1 in Lake Arrowhead.

"We are urgently looking for experienced backcountry hikers to help with a missing person search in the San Bernardino Mountains, specifically on their back side in about [a] 10-square-mile area facing the Mojave desert," Stacia Keller, who is helping organize the search, wrote in an email sent to the LA Times.

Alois Krost, a 62-year-old physics professor, became separated from the group of about 20 others while on the Pinnacle Trail in north Lake Arrowhead.

He's described as an experienced hiker and hunter and was last seen about 5:45 p.m. 10 days ago. He was wearing a light blue long-sleeve shirt, dark blue jeans and lightweight hiking shoes and had no camping equipment with him.

Keller said that all previous rescue attempts have been unsuccessful but a new search is planned for this weekend. If you want to help, contact her at staciake@gmail.com or (805) 367-6144.

If you have information about Krost's location, please call the San Bernardino County Sheriff's Department's Twin Peaks station at (909) 336-0600.

Krost was attending a conference at the UCLA Conference Center at the Lake Arrowhead Resort sheriff's spokeswoman Jodi Miller told the San Bernardino Sun. She said he regularly hiked in the area, having attended the conference for years.

The search is now being handled by the Rim of the World Search and Rescue Team, who are coordinating with the local sheriffs, Miller said.

"It's not your typical forest. This area has a lot of very thick, low-lying brush and rocky formations," Miller told the Sun.
