The country

In 1912, the Novarupta volcano unleashed the largest eruption of the 20th century, burying a lush valley under up to 700 feet of ash and pumice. Today, the Valley of Ten Thousand Smokes is a barren, deeply incised badland carved by the River Lethe and Knife Creek. Surrounding the ash flows are wild coastal stretches and pristine lakes sustaining massive salmon populations.

Why enthusiasts come

While most visitors fly in for an afternoon to watch brown bears fishing at Brooks Falls, backpackers venture into the ash valley for a surreal, otherworldly trek. The sheer desolation, painted canyon walls, and persistent geothermal activity offer an alien environment. It is a striking contrast to Alaska's typical green tundra and glaciated peaks.

Top experiences

Backpacking into the Baked Mountain Huts provides a rudimentary shelter amid the wind-scoured ash plains. Explorers carefully navigate the precipitous gorges carved into the pumice to view the steaming vent of Novarupta itself. Hiking out to the coastal regions reveals an entirely distinct ecosystem dominated by sedge meadows and roaming coastal brown bears.

Planner-relevant notes

Access to the valley requires a float plane to Brooks Camp, followed by a daily 4x4 bus ride to the valley rim at Three Forks. Backcountry permits must be acquired at the Brooks Camp visitor center after mandatory bear orientation. Water sources in the valley are heavily laden with highly abrasive pumice, requiring careful management.

Field notes

Fierce winds whip up blinding ash storms in the valley; bring tightly sealed goggles and durable rain gear.
Standard water filters clog instantly in the ash-choked rivers; rely on alum to settle silt or use snowmelt.
The River Lethe cuts deep, narrow, undercut gorges that are nearly invisible until you are standing on the edge.
Maintain a 50-yard minimum distance from the world's densest concentration of brown bears near the water systems.
