Have you ever heard of Puddingstone?

I first came across puddingstone while visiting cemeteries on St. Joseph Island. My mother and I visited the island in 2022, with plans to visit every cemetery on the island. We started to notice many gravestones made out of this unique stone. We also found large pieces of it left at gravesites, and in one instance possibly used as a temporary marker. I wanted to learn more about this peculiar stone.

During our visit to the island, we had a private tour of Adcock’s Woodland Gardens. The gardens, that sprawl for acres, are filled with beautiful trails and ponds, and hundreds of varieties of plants and flowers. My mother was in heaven. At the end of the tour, as we were heading back to the car, I noticed a cute little wishing well that looked to be made out of the same spotted stone we found in the cemeteries. I asked our tour guide about it. Grant, the owner of Adcock’s Woodland Gardens, was happy to share that this type of rock, native to the St. Joseph Island area is called Puddingstone. 

Puddingstone is everywhere on the island. When we visited Historic Fort St. Joseph, we were greeted by a large boulder of puddingstone at the entrance of the Visitor Centre. Since puddingstone is native to the area, when my mother and I toured the ruins, we spent some time at the water’s edge to see what we could find. Although we did find a few interesting rocks and pebbles, we didn’t find any puddingstone. There was also a sign at the waterfront asking that nothing be taken from the area. It is an archaeological site after all. 

On our way out, we of course checked out the little gift shop. Alas, no puddingstone for sale. I was a little disappointed because there was a beautiful piece of puddingstone sitting at their front desk. It was a baseball-sized chunk, that was mostly all natural and rough except for a smooth clean cut, showing the inside of the stone. 

We left the island without a sample of the stone, but I never forgot about it. I found it curious that it seemed like such a common material on the island, with countless gravestones made from it. I also found it curious that it was also a common grave good on the island. I wanted a little piece of my own.

What is Puddingstone? 

Puddingstone is a jasper conglomerate, a form of sedimentary rock composed of rounded cobblestone and other pebble-sized fragments. Conglomerates are formed by river and ocean wave movement.¹ In Canada, puddingstone is commonly found on St. Joseph Island and in Bruce Mines, Ontario.² It is unique to this part of Algoma.

The name Puddingstone comes from British settlers who were stationed in the area, they thought the pale sedimentary rock, dotted with red and brown jasper, looked like “boiled suet pudding with berries”.³

The Last Spike Stone Cairn, a cairn marking the location of where the last spike was driven for the Canadian Pacific Railway, includes rocks from across Canada. Can you guess what stone was sent from Ontario?

That’s right, it was a piece of puddingstone from Bruce Mines.⁴

The search continues

I checked in with my local gem and mineral shops to see if they carried puddingstone. Surprisingly, they didn’t know what it was. My next thought was to look at any upcoming gem and mineral shows or fairs.

I stopped in at the Galaxy Psychic & Crystal Fair. This weekend event happens annually in the Spring and Fall, but this was my first time attending. I thought there might be some gem and crystal vendors who might be able to help me. Again, no one knew what puddingstone was. One vendor was curious as to what puddingstone was used for. With a Google search, we discovered that it’s thought to have many metaphysical properties and benefits, with dream recall being one.⁵ She suggested that may be why I was searching for it. Maybe? I was more interested in its use in cemeteries. 

I decided it might be time to visit Bruce Mines again. I planned a cemetery road trip for the summer of 2023. The plan was to visit a few cemeteries, check out some antique shops, have a chip truck lunch, and visit the Bruce Mines Museum. I had read a well-timed Back Roads Bill article about some of the oldest graves in Northern Ontario, and there just so happened to be one in Bruce Mines. According to the article, the Bruce Mines Museum has in its collection, a wooden grave marker that is dated October 6th, 1850, and March 20th, 1851, for two victims of the 1849 cholera epidemic.⁶

Unfortunately, the Museum was closed when we arrived. I did double-check the operating hours before going, but I found out later that the Museum was short-staffed that summer, and didn’t always follow their posted hours. But we did get to see more Puddingstone. There are a few large pieces of puddingstone decorating the museum grounds.

My mother and I were both a bit disappointed that we didn’t get to visit the museum, but it wasn’t the end of our trip. We still had some antique shops to visit. We saw a lot of interesting items in the shops, but no puddingstone for sale. I did make sure to ask. At the last shop we visited, my mother found a couple of interesting books, so while she was cashing out I asked the clerk if they had any puddingstone. At this point, I didn’t expect them to have any, and they didn’t. 

But they knew where I could find some!

I was directed to a small artists workshop, that doubles as a gift shop called S&S Creations. To my surprise, the shop was full of puddingstone! The shop features beautiful stained glass artwork, that uses traditional stained glass, but also very thinly cut puddingstone. There was puddingstone in all shapes and forms—from book ends and coasters to large stone pieces and jewelry.

The shop belongs to artist Stephanie and her husband and stone cutter, Steve. With over ten years of experience, they take on projects of all sizes, from furniture and custom work to more delicate art pieces and home accessories. No one up to this point had any idea what puddingstone was, so I was so happy to talk to Stephanie. She told me that she had encountered the same thing, and found it as strange as I did. I guess Puddingstone is a hidden gem!

She asked me how I learned about puddingstone and I told her about my passion for visiting cemeteries, and how the gravestones had piqued my curiosity. It turns out that Stephanie and her shop were responsible for the creation of a lot of the puddingstone markers I had visited. We had a very good conversation, and I was able to finally get my own piece of Puddingstone.

I always find it interesting where cemeteries take me, and this was a fun example of that. There is always something new to be learned. I wonder where cemeteries will take me next?

Thanks for reading!
