MOUNT HOOD, Ore. -- The search continued Monday by air for two missing climbers on Mount Hood after their climbing companion was found dead on Saturday.

The Clackamas County Sheriff's Office issued a press release Saturday evening and said the body of Luke T. Gullberg, 26, of Des Moines, Wash. had been found and brought down off the mountain.

Search and rescue personnel returned to the slopes of Mount Hood Monday to search for the two climbers who have now been stranded on the mountain for three nights.

A Blackhawk helicopter will again join the search. Searchers are working against a weather-driven timeline as a new storm is expected to move into the area after 4 p.m. and will dump more than a foot of snow on the mountain.

A spokesperson for the teams searching on the mountain said multiple groups will be on the mountain in an effort to get personnel above the 10,000 foot mark in areas not searched thus far.

Weather on the mountain cleared in the morning but a new storm expected to drop over a foot of snow on Mount Hood is expected to arrive later in the day, likely as night begins to fall.

Rescuers said avalanche danger is very high at upper elevations.

Just before 2 p.m. Monday, fog and clouds moved back in, halting aerial search efforts and curtailing upper elevation search efforts.

The two other climbers still on the mountain have been identified as Anthony Vietti, 24, of Longview, Washington, and Katie Nolan, 29, of Portland, Oregon. Their condition is not known.

The UH-60 Blackhawk began its search after 9:15 a.m. Sunday with an initial flyover of Reid Glacier which is where searchers believe the two climbers are located. That area is about 9,000 feet in elevation.

In addition, a Civil Air Patrol team from Salem joined the search at about 10:15 a.m. at the request of the Clackamas County Sheriff's office. The patrol said highly trained volunteers in a single-engine aircraft will take digital photographs and transfer them to the Clackamas County Sheriff's office to assist them in directing the search effort.

The sheriff's office also said a U.S. Coast Guard helicopter with thermal imaging equipment out of Astoria will also join the search.

Officials said a digital camera found with the body of Gullberg gave searchers clues where the remaining climbers may be.

Gullberg's grandmother, interviewed in Seattle Saturday, said she is sad that she outlived her grandson. "I am going to miss his smile," Marjorie Gullberg said. "He was just like my son. He did everything for me."

Dennis Simons, a volunteer chaplain for the city of Sandy's fire and police departments met with the families and said they thank everyone for their prayers and support.

"(The families) are grieving and hoping," Simons said. "There are thousands of people around the world praying that Katie and Anthony will be found alive."

He said the three climbers were "vibrant Christians" and "they have dedicated their lives to serving and giving to others."

Nolan has traveled the world rescuing young women from the slave trade, he said.

He said the families are proud of all of them.

"They (the families) have a Christian hope and that's a marvelous thing in that," said Simons. "They know that all of these kids are going to be in Heaven at some time or another."

Mountain rescue crews scrambled Saturday after the three climbers were reported overdue and possibly stranded or lost on Mount Hood near the Reid Glacier.

Strovink said the three climbers were attempting a difficult climb but were well-equipped for winter conditions and are experienced climbers. Family members said that Gullberg has climbed Mount Hood a number of times.

The climbers were due back at Timberline Lodge at 2 p.m. Friday after leaving early in the morning to make their ascent on the mountain. The climbers registered their intentions at the lodge, according to a press release from Strovink.

Friends called authorities after the trio failed to return from their climb.

It was not immediately known if the trio had GPS capabilities or if a phone signal was being used as a beacon to lead rescue teams to their location, reported to be on Reid Glacier on the mountain's west flank.

The cell phone "ping" - a digital record a cell phone makes when it makes contact with a transmission tower - was received at about 1:30 a.m. Saturday.

It was not immediately clear if the signal was just a connection being made or if a text message was sent. If a text message was sent, the content of the message has not been released.

No spoken communication from the climbers via cell phone has been reported. Cell phone reception on the mountain is spotty and weather conditions, described as cold, icy and dangerous by Strovink, can further hamper and signal. Snow is reportedly falling on the mountain.

About 30 volunteers were searching for the climbers Saturday. Other volunteers are manning communications equipment to keep the search coordinated. Strovink said in a press release that family members of the climbers are arriving at Timberline Lodge.

The upper part of the glacier is known to be strewn with crevasses and a serious challenge for climbers. Weather on the mountain Saturday included sub-freezing temperatures the possibility of snow.
