This pre-2017 example of geovandalism (sampling without a permit), shown by paleomagnetic drill holes (red arrows), is a reminder of exceptionally poor judgement that left a scarred archaeological petroglyph site on a Miocene tuff, Nevada, USA. What personal or professional values guided the decision to sample here? What are the consequences? What information or training could have led to better decision-making? Image credit: S. Foss.
