Rocky Mountains after first snow

The Rocky Mountains, or the Rockies, are a major mountain range in western North America. The mountains are eroded by water and glaciers, forming dramatic valleys and peaks. In north Colorado, Rocky Mountain National Park's 415 square miles encompass and protect mountain environments. The photos show the mountains along with the subalpine and alpine worlds, after first snow in 2012 in the area.[Photo/China.org.cn]
