Can you make an Earth sandwich from Edmonton?
No, not from Edmonton itself. The other slice would land in the Indian Ocean, 406 km from the nearest dry land, where the sea floor lies about 4,520 m below the surface. Boats do not count (Sandwich Law § 1.3).
The nearest place from which an exact Earth sandwich is possible is 453 km from Edmonton, 19 km from Bow Island, Canada. Its other slice would go down 111 km from Port-aux-Français, French Southern Territories.
Edmonton is on the The US & Canada ↔ the southern Indian Ocean corridor. Its guide lists where every city on both sides lands and how to make an Earth sandwich there.
How this was worked out: the antipode flips the latitude and moves the longitude by 180°. Land or sea comes from the OpenStreetMap coastline the map uses; the sandwich verdict and elevations come from the verifier's 0.2° grid (Natural Earth land, ETOPO 2022 relief); water names from Natural Earth; towns and populations from GeoNames. The city's position is GeoNames' point for it; a big city's suburbs spread tens of kilometres around that point, and the figures move with them. Generated 2026-09-29.
