California Gold Rush [SEP] Earlier discoveries of gold
The first gold found in California was made on March 9, 1842. Francisco Lopez, a native California, was searching for stray horses. He stopped on the bank of a small creek in what later was known as Placerita Canyon, about east of the present-day Newhall, California, and about northwest of Los Angeles. While the horses grazed, Lopez dug up some wild onions and found a small gold nugget in the roots among the onion bulbs. He looked further and found more gold.
