The predominant theory is that the structure is a result of "igneous intrusion". Imagine the land in the area settling after a major eruption some 40 million years ago, and it where the main vent where the eruption emanates from. As the rocks formed and settled, a larger dome of softer rocks formed over the area and after millennia of erosion had worn away the softer rock, Devils Tower is all that remains. This is still a theory, keep in mind. There are many stories of how the structure came to be.
🤔 Interesting.. Thanks
