Subalpine Fir
Abies lasiocarpa
Subalpine fir grows in one of the most iconic conifer shapes in the mountains — a narrow, spire-like crown that sheds heavy snow before it can break the branches. Near timberline, wind and ice prune it into a low, wind-flagged krummholz form.
Where found
High mountain slopes near timberline throughout the Cascades and Rockies.
Fun facts
- Its narrow spire shape is a textbook adaptation for shedding snow load.
- Near the timberline it can grow as stunted, wind-sculpted krummholz mats.
- Crushed needles carry a strong balsam fragrance.
