If anything the article actually understates how wild it is to not only find this but that many of the surrounding rocks also show the same.
This region is believed to have been formed predominantly by erosion from flows of water or landslides. Native sulfur really only comes from 3 things:
1. Geothermal environments (ex: volcanos)
2. Hydrothermal environments (ex: hotsprings, geysers, etc).
3. Reduction of sulfates into sulfides by bacteria under specific conditions that result in the production of elemental sulfur as a byproduct.
Given that none of these 3 were expected from this area, that leaves a pretty substantial question of how it got there, how it was produced, and if it wasn't produced locally, where it came from.
So again I'm not really sure if it was clickbait by any means.
