Army officer did an Alaska version of Lewis and Clark expedition in 1885
"It is a very remarkable fact that a region under a civilized government for more than a century should remain so completely unknown as the vast territory drained by the Copper, Tanana and Koyukuk Rivers."
So wrote Henry Allen more than a century ago in a government report on his muscle-powered journey from the mouth of the Copper River to the mouth of the Yukon, from where he returned by steamship to the Lower 48. Pushing on when Native guides wouldn't join him for fear of starvation, Allen and a few tattered comrades traveled from near present-day Cordova up to what is now Bettles.
They then turned around and then beat winter to St. Michael, where they jumped the last boat for San Francisco.
