St. Michael volcanic field
The St. Michael volcanic field is a volcanic field located on St. Michael and Stuart Islands in western Alaska, United States. It contains 55 cones and craters, including low broad shield volcanoes and maars.[1] It is considered part of the Bering Sea Volcanic Province.[2]

While there are no written records of eruptions in recent history, Eskimo elders have an account of the mountains smoking in the region. The oldest Eskimo settlements in Western Alaska date to around 200-500 BC, so mountains in the St. Michael volcanic field likely erupted sometime within the last 3,000 years.[2]

gollark: For example, it stores created/updated timestamps in a way which allows them to be looked up more quickly, makes it faster to look up the latest revision of stuff, allows me to do compression (I implemented brotli compression to reduce storage requirements a lot), and allows revisions to have data and represent stuff other than "the page content changed".
gollark: The new version *is* better, even if it involves something like 70 lines more code.
gollark: I've reworked minoteaur's design a bit again because productivity is BEES and happens to other people.```sqlCREATE TABLE pages ( id INTEGER PRIMARY KEY, name TEXT NOT NULL, updated INTEGER NOT NULL, content TEXT NOT NULL);``` I went from that small and thus uncool database thingy to this:```sqlCREATE TABLE versions ( vuuid TEXT PRIMARY KEY COLLATE BINARY, rawSize INTEGER NOT NULL, encoding TEXT, data BLOB NOT NULL);CREATE TABLE pages ( title TEXT PRIMARY KEY, created INTEGER NOT NULL, updated INTEGER NOT NULL, latestVersion TEXT NOT NULL REFERENCES versions(vuuid));CREATE TABLE revisions ( ruuid TEXT PRIMARY KEY COLLATE BINARY, page TEXT NOT NULL REFERENCES pages(title), timestamp INTEGER NOT NULL, type TEXT NOT NULL, data TEXT NOT NULL, -- JSON version TEXT NOT NULL REFERENCES versions(vuuid));CREATE INDEX revisions_page_ix ON revisions(page);```
gollark: Suspicious timing.
