Ten themes, with the sources kept close
These themes are an editorial selection for discovery, not a measured top-ten ranking. Our research considered public audience studies and an illustrative sample of Wikipedia readership. Popularity does not establish the truth of a claim.
Murders & killings
Trace documented killings and their historical setting. A marker is a source location, not a claim about a person’s guilt. Read the linked record for the investigation and any later findings.
Assassinations & attempts
Explore attacks on public figures, including unsuccessful attempts. The category distinguishes these targeted attacks from other killings; source records provide context and outcomes.
Mysteries & reported sightings
Explore disappearances and reported phenomena. A mapped report establishes that a report exists, not that its extraordinary explanation is true. Check the source’s evidence and competing interpretations.
Bombings & mass attacks
Locate documented bombings, mass shootings and other attacks. Records are presented without graphic imagery. Classification can overlap with other themes; each entry appears once in this index.
Natural disasters
Explore earthquakes, storms, floods and other natural hazards. A point locates a reference place for the event, not its full footprint, storm track or impact zone.
Fires & transport disasters
Follow major fires, crashes, collapses and industrial accidents. Historical coordinates and dates can be approximate; use source records for the detailed sequence and investigation.
Battles & military events
Explore battles, raids and other military events within the US map area. A marker is an orientation point, not a reconstruction of troop positions or a battlefield boundary.
Protests & civil rights
Trace marches, strikes, riots and civil-rights events. These labels follow reference records; a short index cannot describe every participant’s aims or experience.
Space, science & invention
Explore documented launches, tests and scientific milestones. Locations mark the event or launch site, not an entire flight path. Dates refer to the selected source event.
Music, sport & culture
Explore concerts, festivals and sporting occasions tied to a date and place. Recurring events are included as specific editions when the source identifies that edition.
What the map does—and does not—claim
Records are imported from Wikidata, with links to the record and its English Wikipedia article. Dates are displayed by year to avoid implying day-level precision. Coordinates are approximate source points; events may cover wider areas. Entries have not all been individually fact-checked by PlaceLayers. The index excludes ordinary venues and institutions, but automated classification may still need corrections.
For a killing, allegation or disputed report, consult the source for the documented status. We do not identify a perpetrator in the map summary or offer speculative accusations. Send a source-backed correction.
