American Adventure in a Seagoing Jeep from the Arctic Circle to Tierra del Fuego, first published in 1957, is the inspiring story of Helen and Frank Schreiber (and their German shepherd, Dinah), who successfully journeyed from the Arctic Circle in Alaska to the southern tip of Tierra del Fuego in Argentina. The couple accomplished this in a modified war-surplus amphibious jeep, capable of traveling on water as well as land. Despite the poor or non-existent roads, innumerable mechanical difficulties, and delays while obscure but necessary documents were processed, the couple reached their southern destination in 18 months of travel. Included are 38 pages of maps and illustrations by co-author Helen Schreiber.

From the dust-jacket: Helen and Frank Schreider are true adventurers. Their dream was to drive the length of the Americas, from the town of Circle, Alaska (just outside the Arctic Circle), to the world's southernmost town, Ushuaia, in Tierra del Fuego. Dinah, their German shepherd, went with them. They are the first people in history to have made this trip. They came back with a whale of a story.
