From the record
“Fort Boise is either of two different locations in the Western United States, both in southwestern Idaho. The first was a Hudson's Bay Company (HBC) trading post near the Snake River on what is now the Oregon border, dating from the era when Idaho was included in the British fur company's Columbia District.”
