The Selknam named their territory (Tierra del Fuego Island) Karukinka by merging the words kar (extreme/very) huhin (land/terrain) and ka (own/ours). This is how the private natural park was also called: Karukinka, which shows us the characteristic landscape conditions of the central zone of the Island, where we enter a timid and green mountain range, led by primary forests of lenga, in addition to mixed forests of lenga and coigue.
On the other hand, you can see various ecosystems such as peat bogs, steppes, scrublands and the coast, where the diversity of the elements of the landscape invite us to stop and observe the details rather than the breadth.
It is a transition landscape between the northern landscape versus the southern landscape of the island, in fact in terms of habitability we could say that it is the most balanced to settle.
Here the seemingly endless steppe is interrupted as timid waves delimit the beginning of the Magallanes Fold and Thrust Belt. With them arise green patches, evidence of a more humid climate and a diversified vegetation.
Rocks emerge from the steppe disturbing the arid monotony. These were formed during a time known as Cretaceous, over eighty million years ago, when the sea covered this territory. Rocks are organised by horizontal layers, parallel to the surface. Each layer took thousands of years to accumulate the sediments that later consolidated the rock that we can see today. Each layer reveals a variation, a discontinuity in the deposition of sediments. It might have been the weather, a sea
level variation, any change that gave place to a layer of new, different sediments. Erosion took away some of the record of these ancient times but left behind these relics to be observed by the road.
