Where every fact comes from

Every factual claim on this site links to one of the 392 sources below. Links were checked on October 22, 2026. Many figures are reused from the founder's two verified plans: FaultLine Utah (opens in a new tab), our sister site for earthquakes, and HiveWatch Utah for outbreaks.

How to read numbers here. Anything marked (estimate) is a planning guess, not a fact. Anything in [brackets] has not been confirmed and should be checked before you rely on it. Official figures carry the "as of" date their source gave. Some federal sites (CDC, BLS, DOI) block automated link checkers; those links were confirmed in a real browser.
