Mystery AtlasGlacial Transport Hypothesis
A minority geological hypothesis, principally advanced by Brian John, that Pleistocene glaciers carried Stonehenge's bluestones most or all of the way from Wales as natural erratics; largely rejected following the absence of confirmed glacial deposits on Salisbury Plain and re-analysis matching key boulders directly to the Welsh quarry sites.

Theories & Explanations
Glacial Transport Hypothesis contradicts Human Bluestone Transport Theory — Identified Welsh quarry sites with human tool marks, and 2024-2025 re-analysis matching the Newall boulder to Craig Rhos-y-felin rather than a glacial deposit, directly weigh against the no-human-effort premise.
