Cambios

South of latitude 39° S you do not find any more a continuous high mountain chain. The higher summits are still above 3000 m but numerous depressions create deep breaches in the main maintain range. These valleys were created by immense glaciers during past glacial periods and remain partly filled by lakes. Many of the passes between Chile and Argentina are in these depressions and often below 1000 m, some are as low as 200 m. Regular rain maintains a very dense forest that is also called [[https://en.wikipedia.org/wiki/Valdivian_temperate_rain_forest Valdivian temperate rain forest]]. Due to this geography the trail goes up and down between these depressions and the island-like mountains that rise out of a wild sea of dense tempered rain forest. Here having a packraft becomes beneficial.
