|The Sacramento River
was the highway into California for emigrants who arrived overland,
starting with John Bidwell in 1841.
With the gold rush, it became the highway to hoped-for riches, as
Forty-niners crossed the Sierra
Nevadas at Goose Lake and raced to strike it rich along one of
the Sacramento's west-flowing tributaries in the area marked as the
"Gold Region" on this 1860's map.
