Magnetic Anomaly

Mimsy January 15, 2019

Brief video description: a series of 8 slides, some still photographs, others animated gifs, combining scans of topographical maps, photographs of the Bogong High Plains, and line drawings featuring eye shapes and black, closely spaced lines. Each slide contains an amorphous, melting, black-bordered white text box. The story written in the text boxes is printed below:

In December 2018, I went hiking on the Bogong High Plains in the Alpine National Park. I went there to visit the magnetic anomaly.

Magnetic anomalies are places where there is a measurable deviation from the Earth’s usual magnetic field. These deviations in the field arise from variations in the chemical composition of local rocks.

I walked to the top of Mt Jim in order to look South over the magnetic anomaly.

As you can see, there is nothing to see.

The disturbance in the field is imperceptible. I saw no change in the rock, and I felt no anomalous bodily pull.

All the same, I’m glad to know that I was looking at the magnetic anomaly, even though I wasn’t seeing it.
