The Rockies have higher peaks than the Appalachian Mountains. The Appalachian mountains are ancient geologically and so have worn down due to erosion, weather and so on. At 6,684 ft., Mt. Mitchell is the highest point in the Appalachians. The Rockies are younger and so have some very high peaks. The Rockies' highest peak is Colorado's Mt. Elbert at 14,440 ft.
Appalachian mountainsThe Appalachian mountains are located in the Eastern part of the USA.
This range, recently traced as far south as New Mexico, extends north thru Newfoundland and crosses the Atlantic, continuing through Scotland. The Appalachian Trail traces the range from north Georgia to Maine.

Before Lewis met up with Clark, he began the expedition on August 30, 1803 in Pittsburgh PA. Lt. William Clark would offer to join Lewis on the expedition weeks later on at Camp Dubois (in present-day Indiana). From there, they sailed down the Ohio River towards St. Louis.
And being that the expedition began in Pittsburgh, states they passed through would include: Pennsylvania, Ohio, West Virginia, Indiana, Kentucky, Illinois, then Missouri, Iowa, Nebraska, South Dakota, North Dakota, Montana, Idaho, Oregon and Washington. So they traveled through 6 states before reaching Missouri, and then 9 more states after that.
If you don't believe me that the expedition began in Pittsburgh and NOT St. Louis, then follow the related link to the Louis and Clark Journals' first entry. As we all know, the common American history textbook likes to smudge the details.
