El Sueño de Oro is a day-by-day account of an expedition for gold in Alaska from August of 1897 to August of 1899. The "log" was created by the leader of the expedition, William Mills Coffee, then of Santa Cruz, California. The log entries create a flowing story of the El Sueño expedition from San Francisco to the Bering Sea and up the Yukon River in Alaska. The El Sueño party searched for gold by dog sled, boat and on foot during the harsh winters of Alaska, where the temperatures were recorded as low as -80 degrees. During the two years there were mutinies, deaths, marriages, amputations, shipwrecks and various accounts of the Alaskan wilderness. The book is an historical account of one man's search for gold, very well documented with photos, maps of probable gold locations and claims, and financial records of the expedition. The Master Carpenter Certificates of the two ships involved with the expedition, "Bessie K" and "El Sueño", are included.
