Can you make an Earth sandwich from Calgary?
Nearly: a sloppy-grade Earth sandwich. The antipode of Calgary lies in the Indian Ocean, 198 km from the nearest dry land. Sandwich Law allows a slice within 200 km of the true antipode, and the verifying grid rates Calgary sloppy, so bread in Calgary and bread near Port-aux-Français, French Southern Territories still count as one sandwich. The elevation bonus depends on the spot chosen for the dry slice.
Calgary 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.
