Geology and History of San Francisco Volcanic Field
The first volcanoes in the San Francisco Volcanic Field began to erupt about 6 million years ago, in an area where the town of Williams is now. Subsequently, a several-mile-wide belt of successively younger eruptions migrated eastward, to the area of modern Flagstaff, and beyond toward the valley of the Little Colorado River. Today, this belt of volcanoes extends about 50 miles from west to east.
