Mexico's magic square

Erle Stanley Gardner

Chock full of b&w and some color photos, Erle Stanley Gardner explores the desert terrain lying south of, and within 150 miles of the US border. His well-funded treks to the land of mountains, lakes, canyons and desert are reached by specially built "sand buggies", pack mules, and even his large GoodYear hot air blimp. He introduces and photos fellow explorers various personages along the way, including the Mayor of San Diego.
