The Rocky Mountains
The Rocky Mountains and the Appalachian Mountains have influenced migration patterns in America. The Rocky Mountains acted as a natural barrier to westward expansion, while the Appalachian Mountains presented a barrier to early settlers moving westward from the eastern colonies.
The pioneers crossed the Appalachian Mountains, the Rocky Mountains, and the Sierra Nevada Mountains during their westward expansion in the United States.
The pioneers crossed the Rocky Mountains during their westward expansion in the 19th century. The Rocky Mountains are a major mountain range in North America that stretches from Canada to the United States.
The Rocky Mountains served as a natural barrier to westward expansion in North America. This rugged mountain range made it difficult for settlers and explorers to cross as they moved toward the Pacific coast.
Mostly the high Rocky mountains, and the Sierra Nevadas. Although rivers were difficult to cross, people found ways to cross them at low water levels or at narrow passages.

There were several halts to westward expansion of the United States. After the French and Indian Wars, the Proclamation of 1763 forbade further westward expansion by the American colonies. This was to prevent displacing Indian tribes and possible future Indian wars. After the American Revolution, the Mississippi River provided a stopping point for expansion. The west side of the river was the French territory of Louisiana. The French and Spanish banned American settlements past this line. After the Louisiana Purchase of 1803, American claims ran all the way to the Rocky Mountains in the northwest and were limited by New Spain (Texas) in the southwest. After the Mexican-American War, America ended roughly at the Rocky Mountains. Finally, after the California Republic was admitted to the Union, the Pacific Ocean was the only limit to westward expansion.
Pioneers crossed the Rocky Mountains in search of land out west during the westward expansion in the 19th century. The journey westward presented many challenges, including harsh weather conditions and rugged terrain.

Jim Bridger is credited with rediscovering the South Pass in Wyoming in the early 19th century while fur trapping in the Rocky Mountains. His rediscovery of the pass became a significant route for pioneers traveling westward during the era of westward expansion in the United States.
