Pre-pandemic, in the austral winter, I drove north out of Lima, up into Peru's highlands to the village of Huamantanga (wa-mon-TONG-a). I was traveling with scientists who were studying local farmers' use of a 1,400-year-old technique to extend water availability into the long dry season.

The rush to claim an undersea mountain range
One of the most mysterious mountain ranges in the world is not visible on any ordinary map. You can’t see it on the most popularly used flat map of the world, the Mercator projection, or on the Peters projection that is a popular (and more accurate) alternative.
