Data layer: Fur Trade Posts of the Oregon Country, 1793
A few caveats before we
get to the download links:
- Only fur trade posts belonging to
the North West Company or the Hudson's Bay Company are in this layer.
- With a few exceptions, only fur
trade posts in the Oregon Country (that is, west of the Rockies)
are in the layer.
- The data field From indicates
the year that the post opened, and the To field indicates
the last year it was operated. In cases where a post was closed
for a while and then re-opened, there are two separate objects in
the data, with separate date ranges.
- Although the fur trade in the Oregon
Country was dominated by the North West Company (NWC) and the Hudson's
Bay Company (HBC), there were other, smaller companies present.
Sometimes the notes field (Location_n) will indicate that
a post was originally built by another fur trading company (such
as the Pacific Fur Company) and subsequently sold to the NWC or
the HBC. As well, Location_n may indicate that a post continued
to operate after being sold by the HBC. In this case, the From
and To fields do not give the years the post existed, but
only the years the post was operated by the NWC or the HBC.
- The projection of the layer is geographic
(lat/long), datum WGS84.
- The layer was made for display at
1:8,000,000, and is really valid for display only at scales smaller
than 1:500,000. Zoom in further than that (to say 1:100,000 or 1:50,000),
and the exact locations of the posts may not be right. (In Google
Earth, a rough equivalent to 1:500,000 is an eye altitude of 150
- "3000" appearing in the
To field indicates that it is unclear (to me, at least) what
year the post stopped operating (for dates after 1872).
- A point offshore appears for the S. S. Beaver,
a steamship operated by the Hudson's Bay Company from 1836 to 1858
as a kind of mobile fur trading post. Its precise location has no

Bruce McIntyre Watson's exhaustively researched book, Lives Lived
West of the Divide, A Biographical Dictionary of Fur Traders Working
West of the Rockies, 1793-1858.
