Both were grazed by cattle from Mexican ranching families. Both had connections to the Pico family, who dominated California politics. Both were traversed by the same immigrant trails and stage roads. And both eventually saw their western portions disappear under Lake Henshaw when the reservoir was completed in 1922.
