However, the most recent and scientifically rigorous study of the pre-collapse SFM, based on measurements of slope angles of uneroded portions of the mountain’s flanks (see figure below) suggests that there were two distinct vents up on top of the volcano back when SFM was at its tallest. Two imposing rhyolite centers are seen at Flagstaff and Show Low-Greer, with Flagstaff's mama 'composite' volcano called the San Francisco Peaks active at 100,000 years ago and Show Low's Mt. In the years that shortly followed the notorious “sideways eruption” of Mount St. Helens in Washington state in 1980 (see computer model graphic of this event below), the collapse of the top and northeast flank of SFM was interpreted by a number of local geologists as having occurred during a similar “sideways eruption”. by a major eruption of a composite volcano. But this sort of hot spot explanation is not a suitable model for the eastward progression of volcanic activity in the SF Volcanic Field. And finally, not only can you see what remains of SFM today, you can also still see portions of the huge avalanche deposit that were created when the top and northeast flank of the mountain came tumbling down.
