Fir

100 metres below the Cabane des Pierres stands the oldest and biggest fir tree in Champsaur. It is a European silver fir (Abies alba). The silver fir is often confused with the spruce (Picea abies). A tip to tell them apart: the spruce has cones that hang under the branch with needles all around the branch, while  the fir   has upright cones and rows of needles  that stand out through having two small white lines underneath them.
