Alaska's size is truly staggering: nearly 600,00 square miles - that's more than twice the size of Texas or four times the size of California. People have come lured by riches beyond their wildest dreams - fur, fish, gold, oil. Others come to lose themselves in a wild land more vast and unforgiving than they could ever imagine. They've come to measure themselves against its challenge. In return, they've endured bitter temps, isolation, and harrowing adventures for the privilege of living there.
