On January 24, 1848, a carpenter named James W. Marshall was building a sawmill for his employer, John Sutter, on the American River. While inspecting the channel, he spotted shimmering flakes of metal. To test his find, he bit into a piece and hammered it between two rocks, proving it was soft, malleable gold. Marshall’s boss, John Sutter, was less thrilled. The Swiss immigrant had built a vast agricultural empire and feared a gold rush would ruin his harvest and his plans. He tried desperately to keep the discovery a secret, hoping to hold back the tide of fortune-seekers for just a few weeks. But in a land of rumor and ambition, a secret of this magnitude was impossible to contain.
The California Gold Rush
James Marshall's 1848 gold find at Sutter's Mill set off a mass migration to California. It made the state rich, cost Native Californians their lands and lives, and left the men who started it broke.

Frequently Asked Questions
Who were the forty-niners?
The forty-niners were the tens of thousands of gold-seekers who migrated to California starting in 1849 following news of the gold discovery. They came from across the United States and the world, undertaking perilous journeys by land and sea to seek their fortunes.
Did everyone who went to California for the Gold Rush get rich?
No, very few miners became wealthy. The most successful entrepreneurs, like Sam Brannan, often made their fortunes by selling overpriced supplies, food, and services to the miners rather than by finding gold themselves.
What was the environmental impact of the Gold Rush?
Early panning was low-impact, but mining quickly became industrialized. Hydraulic mining used high-pressure water jets to wash away entire hillsides, which choked rivers with sediment, destroyed farmland, and caused widespread ecological damage.
