The antipode of
Heshan.

Draw a straight line from Heshan (28.57° N, 112.35° E) through the centre of the Earth and it comes out at 28.57° S, 67.65° W, on dry land in Argentina, 41 km from Famatina. An exact Earth sandwich is possible.

Two globes: one centred on Heshan, one centred on its antipode at 28.57° S, 67.65° W

Can you make an Earth sandwich from Heshan?

Yes: an exact Earth sandwich. Heshan is one of the few large cities with dry land directly opposite it. The grid that verifies submissions rates the spot exact: put a slice down in Heshan and have a friend put one down 41 km from Famatina, Argentina at the same UTC minute, and the whole planet is the filling. The elevation bonus would be about 2,160 m: Heshan sits about 120 m above sea level and the other slice about 2,040 m above sea level.

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.
