California has a Humboldt County and so does Nevada. There is a Humboldt River and a Humboldt Bay and a Humboldt Current. At least eight towns in the United States are named for Humboldt. And then there is the Humboldt Wagon Road, a “current” interest of mine. Who was this Humboldt and what did he do to get his name all over North America?
It’s not because he explored North America. He never saw Humboldt County (either one) or the Humboldt River.
Baron Alexander von Humboldt (1769-1859) was a Prussian naturalist and geographer. He explored Latin America extensively, and briefly visited the United States. meeting fellow natural philosopher (and President) Thomas Jefferson in 1804.
Having just bought the Louisiana Purchase, the U.S. government was eager to have the opinion, knowledge, and maps of the eminent explorer. Unfortunately, Humboldt couldn’t tell Jefferson much about the newly acquired territory, but they must have had some stimulating scientific and political discussions.

1804 Map of the Louisiana Territory. Note the non-existence of the Great Basin and the conflation of the Sierra Nevada with the Rocky Mountains.
So if he never explored North America, how did we get so many features named for him? (There’s a Humboldt Peak in Colorado too.) Blame John C. Fremont. In his day there was no more prestigious name you could bestow than that of the foremost scientist of the era. What had been called Mary’s River, Fremont renamed the Humboldt River.
When gold and silver were discovered in the Nevada Territory, the northwest quadrant of Nevada became known as the Humboldt Mining District, after the river. And when Bidwell in 1861 began planning a wagon road to take freight and passengers to the Humboldt Mining District, he called his road the Humboldt Wagon Road.
Baron von Humboldt was vastly prolific and influential in the 19th century, and is undeservedly obscure today. An excellent recent book about him is The Invention of Nature : the adventures of Alexander von Humboldt, the lost hero of science, by Andrea Wulf.
We started at the Junction (the intersection in downtown Chico where Park Avenue, Main, Broadway and 9th Street meet), where the Humboldt Road begins. Back in the day this was the hub of industry and transportation in Chico.


It’s no wonder that Luzena was amazed when a miner offered her a $5 gold piece, “ma’am, for them biscuit.” According to 
The night before I had cooked my supper on the camp fire, as usual, when a hungry miner, attracted by the unusual sight of a woman, said to me, “I’ll give you five dollars, ma’am, for them biscuit.” It sounded like a fortune to me, and I looked at him to see if he meant it. And as I hesitated at such a remarkable proposition, he repeated his offer to purchase, and said he would give ten dollars for bread made by a woman and laid the shining gold piece in my hand. I made some more biscuit for my family, told my husband of my good fortune, and put the precious coin away as a nest-egg for the wealth we were to gain.


It was a hard march over the desert. The men were tired out, goading on the poor oxen which seemed ready to drop at every step. They were covered with a thick coating of dust, even to the red tongues which hung from their mouths swollen with thirst and heat. While we were yet five miles from the Carson River, the miserable beasts seemed to scent the freshness in the air, and they raised their heads and traveled briskly. When only a half mile of distance intervened, every animal seemed spurred by an invisible imp.
