appalations
The Appalations covers 10 states
There are quite a few, such as the St. Elias range in Alaska, B.C., and the Yukon (where Canada's highest mountain is) and the Cascade range in B.C. and Washington state, but the most famous (and probably most important) is the Rocky Mountains.
A nickname that could be given to the mountain range known as the Appalachians could be the Blue Ridge Mountains. They are labeled this way because of the coloring that they mountains have around dusk, which is typically the best time to get good views of the mountains.
