Detailed explanation-1: -timberline, upper limit of tree growth in mountainous regions or in high latitudes, as in the Arctic. Its location depends largely on temperature but also on soil, drainage, and other factors.

Detailed explanation-2: -Timberline, an upper elevation limit of forests or tree growth in mountainous regions or in high latitudes, occurs below the lower limit of the snowfields. Its location depends largely on temperature but also on soil, drainage, and other factors.

Detailed explanation-3: -Timberline Lodge is located at 6, 000 feet. Silcox Hut is at 7, 000 feet. The highest operation point is the top of Palmer at 8, 540 feet. The lowest operation point is the bottom of Summit Pass at 4, 000 feet.

Detailed explanation-4: -Most ecological studies prefer to differentiate between treeline and timberline. Treeline (or tree limit) designates the limit of tree growth, and timberline (or forest line, forest limit) the limit of closed forests.
