the mount bachelor volcanic chain, southeast of south sister, consists of mount bachelor, which is the largest and northernmost volcano of the group, and a series of cinder cones, lava flows, and three shield volcanoes. the chain runs for and encompasses an area of about , trending from north to south. its volcanoes show significant variation in size and shape, ranging from steep cones produced by mild explosive activity to the gently sloping profiles of shield volcanoes. volcanic vents within the locale show north–northwest–north–northeast-trending trends, which correspond to normal faults (where one side of the fault moves downward relative to the other) in the region, including one at the bachelor chain's southern end. the bachelor chain shows that much of the quaternary cascades in oregon were produced in short bursts of eruptive activity and that mafic shield volcanoes can erupt at equal rates to stratovolcanoes. the volcanoes within the field are fed by shallow, compartmentalized magma chambers.

extinct volcanoes are those that scientists consider unlikely to erupt again because the volcano no longer has a magma supply. examples of extinct volcanoes are many volcanoes on the hawaiian – emperor seamount chain in the pacific ocean (although some volcanoes at the eastern end of the chain are active), hohentwiel in germany, shiprock in new mexico, zuidwal volcano in the netherlands and many volcanoes in italy like monte vulture. edinburgh castle in scotland is famously located atop an extinct volcano. otherwise, whether a volcano is truly extinct is often difficult to determine. since "supervolcano" calderas can have eruptive lifespans sometimes measured in millions of years, a caldera that has not produced an eruption in tens of thousands of years is likely to be considered dormant instead of extinct. some volcanologists refer to extinct volcanoes as inactive, though the term is now more commonly used for dormant volcanoes once thought to be extinct.
