Flora and Fauna. These are the wonders of the Rocky Mountains alpine tundra. The tundra is a type of biome above the tree line. Low temperatures and short growing seasons hinder the growth of trees. Vegetation of dwarf shrubs, sedges, grasses, mosses and tiny brilliant flowers. My introduction to new wonders came with expert guidance from an esteemed naturalist. At 12,000 ft the Trail Ridge Road of the Rocky Mountain National Park brought me to the land above the trees. A heaven of sorts. Had I taken care to tread carefully, stayed on the designated path, not dislodged the exposed soil? Recovery takes hundred of years. My respect for the fragile ecosystem, my regard for my expert guide grew with every moment. Together we spied a line of elks grazing their way steadily up from Moraine Park. Some 300 millions of years ago tectonic activity had formed the natural wonders of the Rocky Mountains.
