Our fall weekend offers memories of walks in the woods on Wiley Hill, where Scoutmaster Art Johnson taught us that nature provided direction finders. One indicator was moss covering the north side of trees and rocks. As noted in a previous column, Proceedings of the National Academy of Sciences reported grazing and resting deer and cattle tend to align themselves with the Earth’s magnetic fields. In 2009, researchers observed 3,000 deer in the Czech Republic, noting that regardless of wind or sunlight, they generally aligned to the magnetic north. Researchers believe many creatures can sense the Earth’s magnetic field and the detection of the field enters into a fundamental role in spatial perception. Even if the creatures move over short distances, the magnetism assisted their navigation. Fastcast: Beautiful.
