Volcanodle
Puzzle #81 was Yoteizan.
Yoteizan is a symmetrical andesitic-to-dacitic stratovolcano NW of Toya caldera. Its summit is truncated by a 700-m-wide crater that is cut on its NW rim by overlapping smaller craters. Deep radial gullies cut the flanks.

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.
