Most great rivers reach a place on their journeys where culture and geography connect; creating a place of tangible power imbued with human reverence, and signaling a clear transition in the life of the river. On the Fraser, that spot is Bridge River Rapids, where the dry interior shifts to wet coast-land and salmon are netted at the base of the roaring rapid. On the Columbia, it is the currently flooded Celilo Falls; gathering place, fishing spot, and historic obstacle to navigation for boats of industry. On the Klamath, the place is Ishi Pishi.

At Ishi Pishi, the Klamath seems to celebrate its very existence in a tumult of whitewater, bellowing a happy roar beneath towering mountainsides. Naturally, the base of the falls has been a good place to catch fish for millennia, contributing to its spiritual status among the Karuk. Kayakers like myself stare transfixed at the long and complicated cataract, contemplating lines that I’ll never attempt. We portaged humbly.

The rapid alone is only part of the Ishi Pishi story. The Salmon River conflues with the Klamath just below, adding a third of the flow. The Klamath turns at the junction, and the scent of mother ocean can sometimes be felt on the steady breeze.

Twenty-three miles farther, and the clear blue Trinity River enters. The Klamath runs northwest creeping tenuously toward the coast. The first redwood trees appear 20 miles from the sea. Gray marine-layer moisture clings to ridgetops. We were a long way from the juniper grasslands and sharp basalt of day one.

After a slow estuary paddle, the re-born river current was a small surprise, ushering us past basking seals, flocking gulls, and gliding pelicans. In 2008, I charged through this break in a poorly judged spontaneous flurry. More measured this time, we pulled onto beach sand just before entering the chaos of river current meeting ocean break.

The mighty Klamath; borne of springs great and small, draining broad lakes, feeding farms, sustaining fish, and now carving through landscapes held captive for the past century, flowed into the great sea and was lost; suddenly, shockingly, beautifully—insignificant.
