The El Dorado Trail tells the story of the 49ers who got to California by going across Mexico. This book was one of The American Trials Series. Unlike many of the other trails in the series that followed an exact route the El Dorado Trail was really a number of routes across Mexico some that started in Vera Cruz and others right on the US-Mexico border. I thought I knew a lot about the California Gold Rush but this part was new to me. I knew about the overland trails from the Missouri River to California and the ways by sea but this was new to me. If I have a complaint it would be that there were no maps provided in the book. I had to stop reading several times and look elsewhere to see where some of the places mentioned were. ( )
