Exploration: a work in progress

The exploration does not end with the first glance, nor the first step, nor the first photograph. Exploration is a collective adventure that continues and rage today. Although geography is only one of the many fronts of our collective exploration, through it, the maps are able to crystallize in an image the state of knowledge of a territory. A reminder of how explorers can change our worldview, both the of one that is physical and palpable and the one that lives only in our minds.

This brief compilation of the cartographic evolution of Tierra del Fuego and Cordillera Darwin illustrates the development of geographic knowledge of this fascinating region. The first maps that we show correspond to the 17th century, compiled by cartographers who collected reports of the few expeditions that entered the area, such as those of Magallanes, Sarmiento, Ladrillero, and L'Hermite among others. There were several centuries of maps with more fiction than reality. They were populated by channels, mountains, sea monsters and people emanating from the stories of sailors returning from one of the most remote corners of the planet. This would change in the first decades of the 19th century, when the British Admiralty recognized the strategic value of the extreme south of America. Between 1926 and 1936, they sent Captains Phillip Parker King and Robert Fitz Roy to explore and map the maze of islands and channels of Patagonia onboard the HMS Adventure and HMS Beagle. For the first time, it was observations and not stories what was turned into the paper. In this way, they produced the first maps that correctly represented the Fuegian geography, but they did not ventured inland, and even a few fjords escaped their scrutiny.

The next great leap in the knowledge of this territory was made by Alberto M. de Agostini, to whom we dedicated a post in this blog a few weeks ago. Passionate mountaineer, explorer and cartographer. He was the first to pay real attention to the mountains, which for him were much more than a reference point for navigation. In his explorations, he discovered the fjords Contraalmirante Martinez and De Agostini. Perhaps the last great geographical discovery in the area made from the surface. Whose is only paralleled by the discovery of the Finland fjord by Väino Auer in 1929.

The next leap in knowledge of the area, arguably the largest but somewhat less romantic, was the result of U.S. Air Force Trimetrogon flights, which in the summer of 1944-1945 photographed almost all of Patagonia from 6,000 meters of altitude, finally revealing the intricate structure of this region. These photographs were used to make the preliminary map at scale 1:250,000, which was published in 1955. The transition from schematic cartography to another with an unprecedented level of detail meant a significant challenge concerning the correct placement of place names in this new frame of reference. Unfortunately, this task was not carried out with the necessary thoroughness, and many of the errors in name placement in the current cartography of the IGM (Instituto Geografico Militar) can be traced back to that transition.

Later, in the 80's, modern photogrammetric flights (Chile 60 and later GEOTEC), allowed to make the current cartography 1: 250,000, 1: 100,000 and 1: 50,000.

However, the methodology used left many blank areas, either due to the presence of clouds or snowy areas that. In such areas, the lack of contrast did not allow the topography to be reconstructed. Unfortunately, there were no significant efforts to fill these topographical gaps, which persist to this day. But more regrettable than the topographic gaps, are the toponymic, historical and heritage voids, a shortcoming that our project has attempted to fill in some of the mountainous areas of Tierra del Fuego through our map UNCHARTED: Cordillera Darwin.
