April 12, 2026 – On this day in 1794, British explorer George Vancouver sailed his ships into what is now called Cook Inlet, chasing one of the great geographic mysteries of his time: a navigable route through North America to the Atlantic: the fabled Northwest Passage.
He didn’t find it there.
Careful soundings, tidal observations, and weeks of charting revealed an enclosed body of water that was neither river nor passage through the continent. It was just an inlet. A bay fed by rivers.
Vancouver would ultimately name it after his former commander, James Cook, who had explored the same waters in 1778 but left lingering uncertainty about what it might have led to.
By the time European ships probed these waters, the region had already been occupied by Alaska Native peoples for thousands of years.
The Dena’ina people had established villages throughout the upper inlet, while the Sugpiaq (Alutiiq) inhabited coastal areas earlier, adapting to a rich environment of salmon, beluga whales, and marine resources.
When James Cook had entered the inlet in 1778, he initially believed it might be a massive river leading inland—or even a passage connecting to northern seas. His frustration grew as the waterway narrowed into what he famously named Turnagain Arm, a dead end that forced him to “turn again.”
Russian fur traders had already been working the region by then, establishing outposts like Fort Nikolaevskaia near the Kenai River in the 1780s. They noted oil seeps and built trade networks, often clashing and negotiating with local Native populations.
But it was Vancouver’s expedition—methodical, disciplined, and backed by years of experience—that settled the geographic question with precision.
After entering the inlet, Vancouver’s crews split into survey parties. He personally explored Knik Arm, while others mapped Turnagain Arm in detail. They tracked tidal extremes, measured depths, and confirmed what Cook had suspected but not definitively proven: the mountains closed in, the waters became shallow, and no passage lay beyond.
By early May 1794, the ships reunited and departed south. The verdict was clear: No Northwest Passage here.

The Russians also married local natives. Historians estimate there were never more than 400 Russians (from Russia) in Alaska at any given time through 1867. But many of them married natives. Still to this day, from Nulato to St. Paul to Unalaska to Sitka, many Alaska Natives have Russian blood.
No No NO!

It is NOT “Cook Inlet”! That is just the imposed nomenclature of white eurocentric colonialist patriarchal misogynistic homophobic anti-trans-gendered imperialists! Its real name is Ek’ntkidniklaqwits’nodklukedniqwxa’kzqw’xqk’w’k, which means “Waterway leading to place of much whiskey” in the language of the Knikq’wak’wazatlnad’nuesqk’xex’ti Indigenous Aboriginal First Nations People.
