Wassillie Trefon Dena'ina Fish Cache

Nail-less Dena’ina fish cache beside the Port Alsworth visitor center

InsideLake Clark National Park

Overview

A compact but fascinating cultural stop, this historic Dena’ina fish cache sits just outside the Port Alsworth Visitor Center. Built without nails or spikes by master woodworker Wassillie Trefon, it’s a hand-hewn, square-notched log structure that shows how salmon and other foods were stored safely for winter. It’s now a rare survivor of a once-common lifeway and was added to the National Register of Historic Places in 2013.

What You’ll See

Look closely at the craftsmanship: tight joinery and clever carpentry—including a vertical spline system that locks the gable logs—hold the building together without metal fasteners. The cache is elevated to keep stored food out of reach of wildlife, a practical design detail that speaks to life here before modern storage.

Brief History

1920: Built at Miller Creek by Wassillie Trefon.
1958: After Trefon’s death, family moved and reassembled it in Nondalton.
2004: Relocated to Port Alsworth and restored to its 1920 form (spruce-and-sod roof; minimal log replacements).
2013: Listed on the National Register of Historic Places.

How to Visit

Port Alsworth is fly-in only; most visitors arrive by floatplane. The cache is an outdoor exhibit you can view year-round right beside the visitor center. There’s no fee to see it. Please be respectful—don’t touch or climb on the structure. Pets are allowed but keep them leashed. Expect to spend anywhere from a quick 5 minutes to about half an hour if you linger over the interpretive panels.

Make It a Stop on a Bigger Day

This pairs perfectly with trails that leave from Port Alsworth: Beaver Pond (3.2 miles round-trip), Tanalian Falls (4 miles), Kontrashibuna Lake (5.5 miles), or the steeper Tanalian Mountain (8.6 miles) if you’re up for a challenge.

Best Time to Visit

Anytime works since it’s outdoors, but the soft light of morning or evening flatters the hand-hewn logs for photos. Summer sees more foot traffic thanks to flight schedules; shoulder seasons are quieter. If you want ranger context, time your visit when the visitor center is open and start there before stepping outside to the cache.

Pros

Elegant nail-less Dena’ina joinery you can examine up close
Easy stop right outside the Port Alsworth Visitor Center

Cons

Brief stop; most visits take 5–45 minutes
No dedicated facilities at the cache itself

Tips

Pair this with a stop inside the Port Alsworth Visitor Center for context before viewing the cache.
Please don’t touch or climb on the structure—the joinery is original and fragile.
Plan flights accordingly—Port Alsworth is fly-in only and schedules can be weather dependent.
Roll this into a Tanalian Falls or Beaver Pond hike to make a fuller half-day.
