A Mount Rainier ranger slid more than 3,000 feet to his death as he helped in efforts to rescue four injured climbers from Texas who fell on a glacier, a National Park Service spokesman said.

Ranger Nick Hall was helping prepare the climbers to be taken from the 14,411-foot Washington state peak when he fell shortly before 5 p.m. Thursday, spokesman Kevin Bacher said.

The 34-year-old Hall didn't respond to attempts to contact him and wasn't moving, and he was dead when other rangers reached him at the 10,000-foot level several hours later, Bacher said.

Park officials notified relatives and other rangers before announcing Hall's death late Thursday.

A Chinook helicopter from Joint Base Lewis-McChord plucked three of the injured climbers off the Cascade Range mountain Thursday night while one member of the party from Waco remained overnight, waiting out a worsening storm in the company of park rangers.

Bacher said all four had injuries that weren't life-threatening. None was immediately identified.

Worsening visibility and 40 mph winds kept rescuers from removing all four climbers late Thursday.

Storms on Mount Rainier are notoriously fierce and obstinate.

About 10,000 people attempt to summit the massive volcano each year, with most doing so in the summer.

The Texas climbers were roped together when they fell on Emmons Glacier on Thursday. The two women at the end of the rope ended up in a crevasse. Rangers who responded to a cellphone call helped them out.

Hall is originally from Patten, Maine, the park spokesman said. He had been with Mount Rainier National Park's climbing program for four years.
