Despite being mere state land, the Revelation Mountains between Lake Clark and Denali National Parks are filled with unnamed peaks far more jagged and glacier-clad than anything in the Sierra or Cascades. The entire range, more than 90 miles long, was largely unknown until the Harvard Mountaineering Club climbed here in 1967. Over the years, we've sampled a lot of Alaskan scenery, but for visual impact and exploratory opportunity, the Revelations are second to none.

The loop described here includes rugged trekking, roped scrambles, and swiftwater paddling in small, inflatable packrafts. Some adventurers have done parts of this route, and Sled Pass was used by ancient Athabaskan Indians, but the trip is not for rookies. Despite the efforts of our strong party, the loop remains unfinished.
To be the first to complete it, you'll need intermediate whitewater paddling skills, as well as climbing and glacier gear, packrafts (, collapsible paddles, and inflatable PFDs. There's at least one deep river ford between dangerous rapids. We recommend going with a guide and allowing 11 to 14 days for the attempt.

Begin from a gravel bar in the narrow gorge of the Stony River's upper East Fork.
