Devil's Arrows Traveled 11 Miles to Brimham Rocks

A recent isotropic analysis has identified Brimham Rocks as the most probable source of the material in question, overturning earlier speculation that the nearby Plumpton Rocks were responsible. The study, conducted by a team of geologists from the University of Leeds, employed advanced isotopic fingerprinting techniques to match trace elements in the sample to the distinct mineral composition of the Brimham outcrop.

The findings, published in the Journal of Geoscience Research, show that the isotopic signatures of strontium, neodymium, and lead in the sample align closely with those found in Brimham Rocks, while showing significant differences from the isotopic profile of Plumpton Rocks. This conclusion has implications for ongoing investigations into the origin of the material, as well as for regional geological mapping and heritage management.

In light of the new evidence, authorities are revising their assessment of the material’s provenance and will update public records accordingly. The study underscores the value of isotopic analysis in resolving questions of geological origin and provides a clearer understanding of the distribution of rock types in the region.
