In which of the following regions in California was gold discovered?

A. San Francisco
B. Los Angeles
C. Sutter's Fort

I'm thinking B.

Oh, wait. It's C isn't it?

Sutter's Mill, actually. It was a sawmill, not a fort.

Gold was discovered in the region known as Sutter's Fort in California. To verify this information, we can break down the options and explore each one:

A. San Francisco: San Francisco played a critical role during the California Gold Rush, as it served as a major port and transportation hub for gold seekers. However, gold was not actually discovered in San Francisco itself.

B. Los Angeles: Los Angeles is not typically associated with the California Gold Rush. Gold was not discovered in this region, so this option is incorrect.

C. Sutter's Fort: Sutter's Fort, located in the present-day city of Sacramento, was the site where gold was first discovered in California in 1848. This discovery eventually led to the massive influx of gold prospectors and the California Gold Rush.

Therefore, the correct answer is C. Sutter's Fort.
