Trip Report! French Creek State Park, June 2026
This was a quick(ish) weekend trip! The park is about an hour away from my house, so I've been there before, and will again, but I'm trying to make each stamp in my State Parks passport book represent a substantial adventure in said park, so I decided to stay the weekend in a cottage in the campground.
The cottages are all pretty much the same, so I didn't take a whole batch of photos of this one, since I already did that for the one at Pinchot.
It was a very hot weekend, so that put some limits on our activities. We ended up spending a lot of time at the Hopewell Furnace National Historic Site, which is surrounded by the state park. It operated from just before the American Revolution through the mid-1800's, processing the region's iron ore into both iron bars and finished products.
I didn't take any picture of the whole furnace, for some reason, but here's a stock one:
The brown shedlike thing on the right is where they loaded ore, charcoal, and limestone into the top of the furnace, which is essentially a big chimney; there are tons of such structures in the area, used for processing various mineral resources in the late 18th through 19th centuries, but this one is enclosed in a wooden structure, which is where they cast the metal.
This is another photo from a tourism site, showing the business end of the furnace, where the molten iron came out.
Now we're back to my own photos.
There in the casting house, they do a program where you get to learn about the sand casting technique that they used to make stoves back in the day, and make a little plaster model of a stove panel.
Here are the tools you get to use. The wooden frame is open on both sides, and there are two flat squares of wood that fit snugly against the open side. You start by putting the metal casting piece on the bottom square, the put the frame over it and pack sand in around it, then put on the other square.
Then there is the tricky part, which is Hold it Gently Like Burger and flip it over. (In the actual industrial process, they would clamp it, since they were setting up a bunch of these to be ready for the pour, and moving them around.) Then you very gently and carefully take the casting piece out, and you're ready to pour!
Here is the metal casting piece; they do occasionally do programs you can watch where they cast actual metal, so I think they may have made these on site? In the actual industrial process, they would get each stove piece carved in wood--which, of course, would start to wear out pretty quickly, being repeatedly covered in sand, but once they had a few clean copies in iron, they could use those as the casting pieces, and put the wooden master away for safekeeping.
And here is my little souvenir stove-plate replica!
Teddy was very patient while we did arts and crafts.
And they gave him his own Junior Ranger badge.
They also have a replica of a charcoal burner's hut. In the 1930's, they got the furnace's last charcoal burner, who at that time was 86 years of age, to come and walk them through the process. They now do a charcoal burn twice a year:
In this spot. The next one is in August, and I've put it on my calendar. I've seen it done on TV, and it might be interesting to see in person; they basically stack wood into a big dome shape, with a chimney going down the middle, cover it all with dirt, set it on fire, and let it smolder for a week.
Here's a selection of stoves that they made in the 1800's. There were several sizes, and different designs you could get. The stove is assembled out of 6 to 12 plates, or basically flat pieces like the model we made, and then assembled.
This one is a little bit special, though, because it is an Illegal Stove. It was made in 1772--before the Revolutionary war. The British government did not allow the colonies to make finished products out of iron; they were supposed to just make iron bars. Those were shipped to Britain to be made into stoves and kettles and whatnot, some of which would be shipped back to the North American colonies for sale.
But this site, which is today about an hour's drive from Philadelphia, in 1772 was sufficiently remote from that center of imperial power that they decided to take the risk of breaking that law, and got away with it.
The owner of the furnace, Mark Bird, would go on to be a Colonel in the Revolutionary war, and the furnace would produce cannons for the war effort--although documents from the period indicate that Bird seriously overpromised on what he'd be able to supply.
This is another shot of the bootleg stove; it's interesting because you can see it's noticeably cruder than the 1800's ones, but still has a lot of ornamentation on it.
Here's a closeup of one of the later ones:
In person the difference is even more obvious; the 1772 one has a noticeably rough surface, while the later ones are smooth, but you can get a pretty good idea from the pictures. The 1800's stoves have the clean lines we associate with mass-produced objects, while the 1772 stove has a rougher, homespun look. But both were made using the same iron from the same furnace, and the same sand-casting process.
