Standing stunned on a Montana mountain ledge, Phil Corah heard the Minnesota man cry out, "Dad! Dad!"
There was no response — just the sound of the wind blowing across the granite face of the mountain at more than 12,000 feet in the air.
On Tuesday, three days later, a search and rescue team recovered the body of Eric Lindberg, 65, of Circle Pines.
On Saturday afternoon, Corah and hiking buddy Grant Brinkman, both of Bozeman, Mont., had watched the Minnesota father and son make their way up Granite Peak, the highest mountain in Montana. They had paused along the mountain's rock face, contemplating whether to climb the last 200 feet up to the summit.
The trek was a lot tougher and more technical than the Bozeman climbers had been led to believe by those who posted on online hiking and climbing forums about their experiences reaching the summit. The two even commiserated about that with the father and son as the Minnesotans passed them Saturday afternoon.
Earlier, Corah and Brinkman had run into other climbers. One couple turned back because they didn't have the gear to navigate the snowfields. Another couple, equipped with ropes and crampons, did reach the summit and said its rock face was actually the easiest part of the climb.
Granite Peak, which rises 12,807 feet in the Beartooth Mountain range north of Yellowstone National Park, is considered one of the most rugged peaks in the Lower 48, according to local authorities and mountain guides. Brinkman, 40, and Corah, 27, were equipped with helmets and ice axes, but like the Minnesota men, they had no ropes.
The Montana men watched Lindberg and his 33-year-old son, Anders, climb the rock face, carefully finding ledges and crevices in which to place a foot and a hand. They appeared agile and experienced.
