Volcanodle
Puzzle #54 was Atuel, Caldera del.
The 30 x 45 km Caldera del Atuel complex, ~30 km NW-SE and 45 km NE-SW, lies just east of the Argentina-Chile border and 18 km SSW of the rim of the Pleistocene Diamante caldera. The western rim in part follows the international border, and the headwaters of the RÃo del Atuel drain to the SE through a wide breach in the caldera rim. The broad floor of the caldera contains with 15 dacitic lava domes and 25 basaltic andesite to andesitic stratovolcanoes and cinder cones.

What the record says
Puzzle 54 ran on 1 Sep 2026 and the answer was Atuel, Caldera del, played with 6 guesses against 8 columns. On the record: Country - Argentina; Region - South America Volcanic Regions; Type - caldera; Tectonic setting - subduction; Elevation - >5000; Rock type - andesite; Historically observed - not-observed. 1 of the 8 columns is blank in the source (Last eruption), so nobody could score it either way.
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.
