3. Cable Mountain. Early settlers of Zion Canyon, having difficulty finding suitable timber within Zion Canyon to build homes, turned to the Canyon rim where enough suitable timber was available. But transporting the timber was a difficult task. As an experiment, they cut a tall 3 foot diameter pine at the top and rolled it over the cliffs edge. When it reached the canyon floor it shattered into kindling. After finding that the logs couldn't survive the fall, they built a cable works atop Cable Mountain to lower the logs to the canyon floor.
