Mount Moran is a mountain in Grand Teton National Park of western Wyoming, United States. The mountain is named for Thomas Moran, an American western frontier landscape artist. Mount Moran dominates the northern section of the Teton Range rising 6,000 feet (1,830 m) above Jackson Lake. Several active glaciers exist on the mountain with Skillet Glacier plainly visible on the monolithic east face. Like Middle Teton in the same range, Mount Moran's face is marked by a distinctive basalt intrusion known as the Black Dike.
Populus tremuloides, the Quaking Aspen or Trembling Aspen, is a deciduous tree native to cooler areas of North America, with the northern limit determined by its intolerance of permafrost. It occurs across Canada in all provinces and territories (with the possible exception of Nunavut). In the United States, it occurs at low elevations as far south as northern Nebraska and central Indiana. Farther west, it grows at high altitudes as far south as Guanajuato, Mexico. In the western United States, this tree rarely survives at elevations lower than 1,500 feet due to the mild winters experienced below that elevation, and is generally found at 5,000-12,000 feet.
The name references the quaking or trembling of the leaves that occurs in even a slight breeze due to the flattened petioles. Other species of Populus have petioles flattened partially along their length, while the Quaking Aspen's are flattened from side to side along the entire length of the petiole. This quaking of the leaves produces a soft sound that many consider a hallmark of the Quaking Aspen. Wikipedia
