Climber missing for days in Montana's Glacier National Park

Search-and-rescue crews continued to comb the verdant hills, mountains and valleys of Glacier National Park on Wednesday for an experienced climber reported missing Sunday.

The missing man was identified as Grant Marcuccio, 32, from the small city of Whitefish, Montana, less than 30 miles west of the park, the National Park Service said in a statement Wednesday.

He left his hiking group while it was traveling on foot from Heavens Peak to McPartland Peak — both are higher than 8,000 feet — and he did not appear at a rendezvous spot, it said.

He had planned to summit both peaks, the park service said.

“He was last seen heading toward McPartland,” the National Park Service said.

Marcuccio was reported missing Sunday night, it said.

It was not clear what could have taken Marcuccio off course. National Weather Service data shows Glacier National Park enjoying a temperature range from lows in the low 50s to highs in the 80s, with light winds and a trace of precipitation measured at times since Sunday.

The search has included park rangers, other search-and-rescue crews, overflights by private search-and-rescue contractor Two Bear Air Rescue and a U.S. Forest Service helicopter crew, the park service said.
