Yellowstone National Park http://www.nps.gov/yell/ Yellowstone is clothed in forests, covering roughly 80 percent of the park. Miles and miles of lodgepole pine forest characterize the park, especially within the confines of the Yellowstone caldera. Also present in the park are extensive areas of forest dominated by subalpine fir and Engelmann spruce, especially in areas underlain by andesites such as the Absaroka Range. These species can also be common in the understory where the canopy is entirely composed of lodgepole pine. Through time, in the absence of fire, the subalpine fir and Engelmann spuce will replace the lodgepole pine, leading to a canopy dominated by these species. At higher elevations, such as the Absaroka Mountains and the Washburn Range, whitebark pine becomes a significant component of the forest. In the upper subalpine zone, whitebark pine, Engelmann spruce, and subalpine fir often grow in small areas separated by subalpine meadows.

Grand Tetons National Park http://www.nps.gov/grte/  Located in northwestern Wyoming, Grand Teton National Park protects stunning mountain scenery and a diverse array of wildlife. The central feature of the park is the Teton Range — an active, fault-block, 40-mile-long mountain front. The range includes eight peaks over 12,000 feet (3,658 m), including the Grand Teton at 13,770 feet (4,198 m). Seven morainal lakes run along the base of the range, and more than 100 alpine lakes can be found in the backcountry.
