Volcanodle
Puzzle #89 was Omanago Group.
The Omanago volcano group consists of a series of five closely spaced lava domes that were constructed north and NW of Nantai volcano in Nikko National Park. The highest of the dacitic domes is Omanago, which later erupted andesitic lavas. The Mitsudake dome, which overlooks the hot spring resort of Lake Yunoko, was radiocarbon dated at about 5,000 years ago.

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.
