Carbajal Valley
The Carbajal Valley is a valley in the Fuegian Andes of southern Tierra del Fuego Province, Argentina. The Carbajal valley is approximately long, running west to east, between the Alvear mountain range to the north and the Vinciguerra range to the south. Andes peak heights in the region are generally less than above sea level.
Argentine Route 3 runs diagonally through Ushuaia along the Río Olivia past the west base of Mount Olivia and around the northwestern and northern base of Monte Cinco Hermanos.
Topography
During the Last Glacial Maximum (LGM), approximately 20,000 years ago, a valley glacier carved the Carbajal-Tierra Mayor valley from northwest to southeast, with an ice tongue forking south along the Valle Río Olivia into the Beagle Channel immediately to the east of Ushuaia. Based on the geological study of the erosion patterns, the Carbajal glacier’s ice thickness was. Several existing glaciers were tributaries of the Carbajal glacier.In the early Holocene period, by 10,300 years ago, ice had receded from the valley walls and vegetation was growing. By the middle Holocene period, forest growth was expanding.
The nearly U-shaped valley floor is covered with Sphagnum peat bogs and poorly drained mires.
