Yesterday's answer
Volcanodle was Blue Lake Crater.
Blue Lake Crater is a series of at least three overlapping explosion craters along a NE trend slightly east of the crest of the Cascade Range in the state of Oregon. Explosions through pre-existing bedrock about 1,300 years ago deposited basaltic bombs and cinders, and spread tephra to the E and SE during perhaps the youngest eruption in the Santiam and McKenzie Passes region. The eruption created an elongated, steep-walled crater with a low rim that rises about 50 m above adjacent topography.

What the record says
Puzzle 104 ran on 21 Oct 2026 and the answer was Blue Lake Crater, played with 6 guesses against 8 columns. On the record: Country - United States; Region - North America Volcanic Regions; Type - other; Tectonic setting - subduction; Elevation - 500-1500; Last eruption - older-Holocene; Rock type - basalt; Historically observed - observed.
Beyond the grid the record adds Holocene eruptions recorded - 1 eruption.
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.
