A Delicate Balance
The Old Man was made of five slabs of Conway granite balanced one atop another. As shown in this drawing of the south side of the stone face, but hidden in the familiar view from the north, was a cavern about four feet wide behind the Old Manís chin (Block 5). which ran almost the entire width of the Old manís face. About 80% of the chin block hung out over the cliff. Thus, just about two feet of the chin was anchored to the cliff, held there only by the weight of the four slabs above it. Amazingly, the other four slabs were positioned so that the center of gravity of the chin block was within that two foot span. This allowed the Old Man to balance on its chin for centuries.
1 – The Old Manís visage was delicately balanced on the chin, with weight of upper blocks holding the chin in place.
2 – Water damage eventually moved the chinís center of gravity, causing the chin block to move slightly forward past the cliff face. When this happened, the chin toppled down the cliff.
3 & 4 – With
5 – The forehead slab, left unsupported, quickly followed and the Old Man of the Mountain, as we had known it, was gone.
A photograph taken shortly after the Old Manís disappearance provides further evidence that water damage to the granite through the years caused the rocks to break and tumble rather than to slide. What appears to be dirt actually is granite that was “rooted” by water. (The local granite is loaded with the mineral potash feldspar, which is particularly reactive with water.
