which mountains are higher the rockies or the appalachians
Appalachian Mountains The Appalachian Mountains[a] (French: les Appalaches), often called the Appalachians, are a system of mountains in eastern North America. The Appalachians first formed roughly 480 million years ago during the Ordovician Period. They once reached elevations similar to those of the Alps and the Rocky Mountains before experiencing natural erosion.[4][5] The Appalachian chain is a barrier to east-west travel, as it forms a series of alternating ridgelines and valleys oriented in opposition to most highways and railroads running east-west.
Pikes Peak Pikes Peak is the highest summit of the southern Front Range of the Rocky Mountains, in North America. The ultra-prominent 14,115-foot (4,302.31 m) fourteener is located in Pike National Forest, 12.0 miles (19.3 km) west by south (bearing 263°) of downtown Colorado Springs, Colorado. The mountain is named in honor of American explorer Zebulon Pike, who was unable to reach the summit. The summit is higher than any point in the United States east of its longitude.[2][3]
