Otish Mountains

The Otish Mountains rise northeast of Lake Mistassini, their peaks divided by valleys, streams and sheltered lakes. Alpine plants cover the heights, which reach nearly 1,130 metres at Mount Yapeitso. The Otish River has its source among these hills. The name is related to an Indigenous word for a small mountain; in 1731 the Jesuit Pierre-Michel Laure marked the range on a map as “M. Ouatchish,” placing it northeast of Lake Mistassini.
