Subalpine Fir
Abies lasiocarpaAlso known as Rocky Mountain Fir, Balsam, White Fir, Alpine Fir
Subalpine fir dominates high-altitude timberlines across western North America, often forming stunted, windswept forms called krummholz near the tree line. Its narrow, spire-like crown sheds heavy winter snowpacks efficiently while upright, deep purple cones ripen in the upper branches. Resin blisters dotting the smooth grey bark emit a sharp, aromatic fragrance when punctured.

Responsible observation
- Cone Spotting: Look high in the upper crown during late summer to see upright purple cones before they disintegrate.
- Bark Resin: Avoid leaning against trunks, as sticky resin blisters easily pop and stain clothes.
- Krummholz Habit: Look for sprawling, bush-like mats at extreme windswept timberlines where trees cannot grow tall.
