Astor withdrew from American Fur Company in 1834. It split up and eventually fell into decline as silk hats became more fashionable than beaver pelts. The post at Fond du Lac ceased operation by 1847. Its ruins were removed at the turn of the 20th century. The site is now a fairly unimpressive, but historically significant, city park. It bears the name Historical Park, though in the past it’s been known as J.J. Astor Park and Heritage Park.
In the 1930s a replica of the trading post was built farther upstream, in Chamber’s Grove Park, as a tourist attraction. That closed in 1968.
The postcard shown here is postmarked Dec. 31, 1952. On the back side “Miss Porter” writes to Gary Byce of Duluth:
Thank you so much for the candy. It was delicious and we enjoyed it much.
I hope you are having a wonderful vacation. I am.
Best wishes for a happy New Year.
Below are a few modern-day images of Historical Park.
