Devils Tower rises about 867 feet above its base in Crook County, Wyoming, a single mass of phonolite porphyry split into giant columns several feet wide, some reported up to ten. Geologists agree it began as magma trapped underground, yet more than a century of published fieldwork has not settled which model explains how it cooled.

A laccolith, a volcanic neck, a stock, a maar-diatreme crater, each has real evidence and a real gap, and the erosion that exposed the tower is the same erosion that erased the proof needed to choose between them. This episode weighs all four models against what the rock, the nations who call it Bear Lodge, and the National Park Service actually say.

🔥 In this video you will discover:
✅ Why NPS says geologists cannot agree how the tower cooled
✅ The 1961 potassium-argon dating result from Bassett's Science study
✅ What the 2015 Geosphere maar-diatreme study by Závada proposes
✅ Why the laccolith model's key evidence washed downstream
✅ How Lt. Col. Richard Irving Dodge's 1875 translation became Devils Tower
✅ Why more than twenty nations still call it Bear Lodge
✅ What the 1998 Bear Lodge v Babbitt climbing case decided

📖 A look at the published, unresolved scientific dispute over how Devils Tower formed, and the sacred name debate that runs alongside it.
