Why did trappers from the US head west to California?

Trappers from the U.S. headed west to California primarily in search of fur-bearing animals, driven by the lucrative fur trade during the early 19th century. The region's abundant Natural Resources, including beavers and other wildlife, offered significant economic opportunities. Additionally, the allure of new territories, the promise of adventure, and the desire for land and wealth motivated many to explore the western frontier. The discovery of gold in 1848 further intensified the westward migration, attracting a diverse group seeking fortune and a new life.
