At the mouth of Afton Canyon, it may be easier to visualize a great lake, Lake Manix, breaching its shores and its waters carving this terrible and yet beautiful gorge through the layers of the millions and millions of years of earth that have gone before. At least at one time, it was believed this all occurred rapidly, over the course of a few weeks, raging in colossal destruction. Now, I believe, the evidence shows it was not just one seismic event that provoked this tearing of the landscape, that it took place over thousands of years driven on by multiple events and changes in climate.
