Mountain Hemlock grows up to 15 m tall and is a evergreen conifer with dark bluish-green needles growing around the twig. The bark is dark reddish-brown and becomes more and more scaly with age. The Hemlock grows in mid to high elevations as well as lower elevations further north and on cool and wet locations, which makes it a common species in Coastal Mountain range forests. The different parts of the Mountain Hemlock have been used by native people. The needles have been used for spice and tea, the wood for carvings and utensils and they used the bark for food and as red dye for hides.
