The tree line in the Rocky Mountains typically ranges between 11,000 and 12,000 feet (3,350 to 3,650 meters) above sea level. However, this can vary depending on factors such as latitude, local climate, and soil conditions.
The tree line is the elevation above which trees cannot grow due to harsh environmental conditions like cold temperatures, strong winds, and poor soil. In the Rocky Mountains, the tree line is generally higher in the southern parts of the range compared to the northern areas.
At these high elevations, you’ll find hardy species like the Engelmann spruce and subalpine fir, which are adapted to survive in such extreme conditions. Above the tree line, the landscape transitions into alpine tundra, characterized by low-growing plants and shrubs.
