The Vancouver expedition had left Hawaiʻi for…
June 1794 CE
They had spent late April and early May charting the furthest reaches of what Vancouver renamed Cook Inlet; Vancouver himself had reached the head of Knik Arm, while Whidbey had reached the head of Turnagain Arm.
The last days of May and the second half of June have been spent charting Prince William Sound: Whidbey the western half to Bligh Island, and Johnstone from there east and southwards.
From here the expedition had worked its way eastward.
The weather is often freezing, as a result of which not only their store of live turtles (kept for meat) but Menzies' quarterdeck greenhouse had frozen, killing all his plants.
While at Cook Inlet and Prince William Sound, they traded with the Russian settlements and natives alike.
