Volcanodle
Puzzle #33 was Hakkodasan.
The Hakkodasan complex includes at least 17 stratovolcanoes and lava domes south of Mutsu Bay at the northern end of Honshu. The NE rim of an 8-km-wide Pleistocene caldera forms an arcuate ridge across a flat caldera-floor moat NE of the Hakkoda group volcanoes, which bury the SE caldera wall. A northern group of volcanoes, constructed within the caldera, appears to be younger.

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.
