Puzzle #12 was Lassen Volcanic Center.
The Lassen Volcanic Center consists of the andesitic Brokeoff stratovolcano SW of Lassen Peak, a dacitic lava dome field, peripheral small andesitic shield volcanoes, and large lava flows, primarily on the Central Plateau NE of Lassen Peak. A series of eruptions from Lassen Peak from 1914 to 1917 is the most recent eruptive activity in the southern Cascade Range.

Volcanodle builds its record from Global Volcanism Program, Smithsonian Institution (Venzke, E. (ed.), Volcanoes of the World, volcano.si.edu). The description above comes from the same place the game credits on every reveal: A verbatim excerpt of the volcano's GVP Geological Summary. The puzzle itself is still playable in the archive, and every answer that has been and gone is listed on the past-answers page.
