Other active sites include Mount Shasta and Lassen Volcanic Center in Northern California, as well as Long Valley Volcanic Region near Mammoth Lakes, and Coso Volcanic Field, east of a string of unincorporated communities along Highway 395. Sunset Crater may have erupted during the winter of the year 1064-1065. There is good evidence that late collapse of the east flank occurred at San Francisco Mountain. This is in line with the general southwestward movement of the North American Plate as it slides west over lithospheric zone that spawn eruptions. The volcanic field is also the site of some of the USA's most recent volcanic activity, the formation of Sunset Crater cinder cone around AD 1100. During its approximately 6-million-year history, this field has produced more than 600 volcanoes, and almost all of the hills and mountains between Flagstaff and the Grand Canyon are representative of the San Francisco Volcanic Field.
