“While 3-inch turnbuckles had been bolted into the Old Man to try and prevent it from falling, the actual strength of the granite was degraded over centuries, and that’s probably why it collapsed.”įundraising began for a memorial soon after the Old Man tumbled. “The Old Man of the Mountain may have weighed nearly 2,000 tons when it collapsed,” said Maclay, who spoke about his research Wednesday.
Viewers can see the model up close and at different angles. He also used original film negatives taken between 19 that documented the formation and area. He was assisted by Dartmouth collaborators who used a drone to do aerial surveys. Maclay, who is studying soil and rock samples from the mountain, created an online interactive 3D model of the Old Man as it was.
A research project led by Dartmouth College graduate student Matthew Maclay estimates it was 750 cubic meters - “more volume than five school buses,” he said. Today, there’s a better sense of the volume and mass of rock that was lost when the Old Man fell from Cannon Mountain. Lakeville North's Nolan Winter named Minn.
