Podcast - Salmon River High Adventure Base - Interview with Camp Director Al Davis

The Salmon River High Adventure Base is  a joint venture between Grand Teton Council and the Mountain West Council.

Idaho's Salmon River, known as the "River of No Return," is one of the most unique in the world. Originating in the mountains of central Idaho, it flows through some of the most beautiful and pristine land in the United States before reaching its confluence with the Snake River. It is a free-flowing river, without a single dam anywhere on the 425 miles of its main steam. It is one of the longest such rivers in the continental United States, second only to the Yellowstone. Also, excepting Alaska, it is the longest undammed river contained entirely in a single state. 
The exact origins of the Salmon's nickname are lost to history. Some credit Lewis and Clark after they turned back, the only obstacle during their entire exploration they retreated from. Others say it was early pioneers who settled along the river as farmers and miners. Whoever first coined the phrase, the name is fitting. On average, the river loses nearly 20 feet of elevation for every mile, making for some intense whitewater. It also travels through the Frank Church-River of No Return Wilderness, the second-largest wilderness in the lower 48.
