| Going above treeline requires special care, as conditions are harsher and more unpredictable. |
| As shown in Fig.1, the northern limit for boreal forest proper deviates to the south of the treeline for individual stands of trees. |
| After two hours' rock hopping the forest starts to yield to scrub and eventually meadow as we emerge above the treeline. |
| As elevation increases, trees become stunted and above the treeline only shrubs, moss, lichen and herbs are found. |
| Inuit near the treeline, for example, could access pine, the inner bark of which is rich in acetylsalicylic acid. |
| To really appreciate the area, hike above the treeline on a mountain slope where you can see sagebrush and several other alpine flowers. |
