Yukon-Charley Rivers National Preserve  

One hundred and fifteen miles of the powerfully swift and silty Yukon are protected in the preserve, along with the entire length of the Charley River, a rare, clear-flowing waterway that many consider to be the most spectacular in Alaska. Miners flocked to the region during the gold rush, and old cabins and relics from that era are common.

Size: 2.5 million acres. Located along the Canadian border between the tiny mining towns of Eagle and Circle, in central Alaska.
