VANCOUVER, Wash. -- The two young girls who spent the night in the wilderness after they got separated from their dad and brother during a family hike in Clark County were found alive, authorities told KGW.

Members of the Volcano Search Team said they found the girls near where Tarbell Trail crosses Coyote Creek, about 1.5 miles away from where their dad and brother were rescued several hours earlier.

"The girls are tired but fine," Sgt. Steve Shea with the Clark County Sheriff's Office told a crowd of reporters and searchers, moments after word came from rescuers that the girls were safe.

Then, just before 12:30, a red SUV pulled up to the trailhead and the two girls stepped out, looking tired but otherwise fine. They were escorted straight to a waiting ambulance to be checked over.

Family had gone on a dayhike

The girls' father, Gintaras Jonas Braciulis, called 9-1-1 around 7:30 p.m., Sunday night. He said he had gone hiking with his three children but got lost and then got separated from his seven- and 10-year-old daughters.

Sgt. Steve Shea said the family had been hiking on Mt. Tarbell, which he described as "very remote."

The Clark County Sheriff's Office Search and Rescue team found Gintaras Jonas Braciulis and his 15-year-old son around 1 a.m., after he led them in using his cell phone. The search continued all night for the girls.

The family had planned to do just a dayhike when they left the trailhead Sunday. But the girls disappeared around 3 p.m., so the dad and son searched for them until around 7 p.m., when he decided to call for help.

Authorities said the girls did have a red sweatshirt and a backpack with some snacks in it, but no flashlight. They were unsure whether the girls had any water.

Clark County was getting assistance from Silver star search and rescue, air support units, and several area dog teams. The girls' dad also went back into the trail with rescuers, to aid in the search.

Temperatures did not dip into extremely cold conditions overnight, increasing the girls' chance for survival.
