Yellowstone Supervolcano Cover-Up
Claims that the US government or USGS is concealing evidence of an imminent Yellowstone supervolcano eruption that would devastate North America, or that seismic and geothermal data are being misrepresented to prevent public panic. The USGS Yellowstone Volcano Observatory (YVO) publishes its monitoring data in real time. The current probability of a large-scale Yellowstone eruption in any given year is approximately 1 in 730,000.

D.B. Cooper: The Unsolved Hijacking
On 24 November 1971, a man using the alias "Dan Cooper" hijacked Northwest Orient Flight 305, extorted $200,000 in ransom, and parachuted from the aircraft over the Washington-Oregon wilderness, never to be identified. The FBI investigated more than 1,000 suspects over 45 years before formally suspending the investigation in 2016. In 2011, a citizen-science analysis of a partial ransom-bill find and particles on Cooper's abandoned tie produced new leads that also proved inconclusive.

History & Ancient CivilizationsDebunked
The Bermuda Triangle
Claims that an area of the North Atlantic bounded roughly by Miami, Bermuda, and Puerto Rico experiences an anomalous rate of ship and aircraft disappearances attributable to supernatural forces, extraterrestrials, or unknown natural phenomena. Lloyd's of London (1975) found no anomalous loss rate in the region, and researcher Larry Kusche demonstrated that many celebrated disappearances were misreported, occurred outside the claimed boundaries, or never happened.
