Mount Rainier National Park in Washington state encompasses 236,381 acres (369.35 sq mi; 956.60 km2) including all of Mount Rainier, a 14,411-foot (4,392 m) stratovolcano. The mountain rises abruptly from the surrounding land with elevations in the park ranging from 1,600 feet to over 14,000 feet (490 – 4,300 m). The highest point in the Cascade Range, around it are valleys, waterfalls, subalpine meadows, old-growth forest and more than 25 glaciers. The volcano is often shrouded in clouds that dump enormous amounts of rain and snow on the peak every year. Mount Rainier is circled by the Wonderland Trail and is covered by several glaciers and snowfields totaling some 35 square miles (91 km2). Carbon Glacier is the largest glacier by volume in the contiguous United States, while Emmons Glacier is the largest glacier by area.
