[A superimposition of 23 significant journeys. (click to view large)]

Stumbling upon a map produced by GOOD magazine (and executed by the reliable graphics of Graham Roberts), suggests the power of historic routes to mark the very teritory in which they navigate - whether it be land, water, or air. Some chartered in open territories are literally exploratory while others are massive infrastructures intended to cheat time-space relationships, or geographic hurdles.

One interesting trend here is the fact that 20 out of the 23 routes highlighted predominately move horizontally. Leaving only three routes - De Soto's Expedition, Pan-American Highway, and Pizzaro's travels in Peru - with longitudinal aspirations. The radical climatological differences of a longitudinal route providing a deterrent. Additionally, the Equator forms a natural mean center to all of these travels, while the size of South America and Africa as a barrier to maritime travel becomes overtly evident.

The Pan-American Highway is unique piece of infrastructure extending from Prudhoe, Alaska to Ushuaia, Argentina. The highway charts the dominant habitable climates and ecologies on the globe. One obstruction prevents it from being an entirely continuous system: The Darien Gap, a 87 km stretch of rainforest.
