"The saga of the great mule teams and giant wagons that are today's romantic symbol of Death Valley began long before the first muleskinner piloted his lumbering borax freighters out of the Big Sink. Its roots were in that night when Aaron and Rosie Winters crouched in their darkened camp at Furnace Creek and read their future in the green-flickering flame of burning borax. But its seed went farther back." First published in 1955, this is a wonderful book on the mule team days in California's Death Valley during the 19th century. It contains observations on the natural history of mules and muleskinners, and the mining of desert borax. There is also a reprint of Henry G. Hanks' Report on Death Valley from 1883.
