Searchers are looking for a missing Anchorage, Alaska, woman who was last seen early on July 8 at a campground on the Seward Highway, according to Alaska State Troopers (AST).

Troopers were notified Wednesday that 43-year-old Valerie Sifsof had been camping Saturday with another person at the Granite Creek Campground, near Mile 64 of the Seward, when she became upset and walked away from the campground at about midnight, KTUU-TV, Anchorage, reported.

The other camper tried to find Sifsof, who reportedly left behind her keys, identification and cellphone, but left the campground at about noon Sunday. Sifsof was reported missing after she didn’t contact friends or family. Her family says the other camper was her boyfriend.

Troopers’ Helo-1 is working with the Alaska Mountain Rescue Group in an effort to find Sifsof, and MATSAR Search and Rescue personnel with search dogs combing the area.

Since news of her disappearance, her family has been actively searching the area, combing the dense brush that surrounds the campgrounds.

On Thursday, troopers searched by air and ground, and brought in three teams of search dogs. Family members continued searching into the night with no sign of any clues to where she might be.

“The scary part of the whole thing is the weather has been cold and wet — not good for being outside,” said her father, Victor Sifsof.

Troopers will resume the search Friday morning. They say they plan to raft the nearby Granite Creek and Six Mile Creek with search dogs.Sifsof stands 5 feet, 5 inches tall and has black hair and brown eyes. She was last seen wearing a black sweatshirt-type jacket, blue sweatpants and black boots.

AST spokesperson Megan Peters said there have been unconfirmed reports of Sifsof seen in the Anchorage area, but search efforts will continue.

Anyone with information on Sifsof’s whereabouts is asked to contact AST in Girdwood at (907) 783-0972 or the Alaska Bureau of Investigation’s Missing Persons Clearinghouse at (907) 269-5497.
