This important and early map of the California Gold Rush was made from Lt. Derby's original sketch by J. Mc. H. Hollingsworth in the office of the 10th Military Dept. covers central California including San Francisco, Monterey, east to the Sierra foothills and the diggings, with the various mining camps named and shown.
George Horatio Derby, born at Dedham, Massachusetts, April 2, 1823, graduated from West Point in 1846, and after a tour of duty in the East and Middle West, came to California in 1849. He accompanied Brig Genl. Bennet Riley on a tour of the gold districts during the summer of that year, and his `Sketch of General Riley's Route' was the result of that journey...."
It is historically important, not only for its depiction of Gen. Riley's route, but because it names, for the first time, certain actual mining camps in the middle Sierra foothills; Mormon Island (misspelled Mormont), Coloma (mislabeled Colluma), Curtis, Sullivan's, Corons, Jamestown, Woods and Sonora. The entire route of the Riley party is noted, with the dates of their visits to the various camps, and covers the region from Monterrey Bay, north to Sacramento and east to the gold diggings.
