About this quiz
Each round draws 10 of 22 places where American history happened, from Fort Necessity in 1754 to the Stonewall Uprising in 1969. Every one is preserved today as a national park site. Distances are real kilometres along the Earth's surface, worked out from where you clicked, so the score is the same on a phone and on a big screen.
- A pin within 40 km keeps all 100 points. From there the points fall in a straight line to nothing at 800 km.
- The state lines are drawn but nothing is named, so knowing the state is half the answer.
- After each pin the real spot is shown with a line to your click.
- The first round of each day is the same for everyone. Play again for a fresh draw.

Note on the data. Each event, its year and its coordinates come from the National Park Service's own record of the park that preserves the site (description, latitude and longitude in the NPS Data API), read on 3 October 2026. A year is shown only where the park's record states it; otherwise the second line names the war or the building. Distances are great circle distances on a sphere of radius 6371 km, from the click turned back into latitude and longitude through the map's Albers projection. Sites in Alaska and Hawaii are left out because those states are insets. The 50 states are those on the Census Bureau's state code list, leaving out the District of Columbia and the territories. The map is drawn from the Census Bureau's public domain cartographic boundary files, with Alaska and Hawaii moved and rescaled into the lower left corner.
