Terra is a cartography studio. Behind this cartouche, one mountain is being redrawn live — the same ridge our founders triangulated by mule and theodolite, now running in your browser.

Rendering I / III
Contour
Isolines every forty metres, majors every two hundred. The oldest trick in the drawer: pretend the mountain is an onion.
Legend
Every mark is a promise.
A map symbol is a contract between the drawer and the walker. These are the four we've kept since 1928.
Contour
Forty vertical metres between neighbours. Where they crowd, respect them.
Water
Drawn in its own ink since the flood of '31 taught us not to economise.
Survey point
A place someone stood, shivering, to make the rest of the sheet honest.
Summit
The reason for the whole sheet, usually drawn last, always climbed first.
