Eagle Furnace, Clarion County

This is a furnace I came across today while working. I noticed a road called Eagle Furnace Road and decided that this would be a good place to check out really quick. The furnace isn't far from the road but it is a little tricky finding it. Eagle Furnace sits on a hill above Canoe Creek. The furnace itself looks like it could collapse over the hill and I'm sure it's going to sooner or later. The huge stone supports above the arches, that hold up the furnace, are all cracked or broken. 

 

Eagle Furnace was constructed in 1846 by Curll, Kribbs and Company. According to "A Guide To The Old Stone Blast Furnaces Of Western Pennsylvania", It was a cold blast charcoal furnace with one tuyere and an 8 foot bosh. 1n 1850 Kribbs and Reynolds are listed as owning the furnace. It went out of blast in 1858 and has been sitting all alone on the hillside ever since. In 1849 the furnace produced 850 tons of iron. It's original height was 32 feet, I didn't measure it but it seemed considerably shorter than that today. I guess after 158 years of sitting on the side of a hill we're lucky to have anything. This furnace has 2 arches, both are partially collapsed. 

 

My photos are not very detailed. They were taken with a cell phone.

The arch on the north end of the furnace. The pipe running in front of it goes down to the creek and up over the hill. I'm not sure what it's for. I tripped over it when I first started looking for this furnace.

A close up of the inside of the arch. It's still holding on.

The stone that remains on the arch is incredible cut stone. Very detailed. The type you see on old bridges and retaining walls.

The other side of the arch.

 

This would be the northeast corner. Between the two arched sides.

The eastern arch. Also in danger of collapsing.

A closeup of the cut stone on the eastern arch. Incredible.

Just a matter of time...

Closeup of the remaining stones on one of the corners.

It does look like the nice cut stones were hauled away at some point. These stones look like fill.

A tree growing out of the stones.

On the north end is the depression which looks like it could have been part of the race.

Four Westmoreland County Iron Furnaces

Today was a great day to get out and do some pre-coke oven season exploring. Summer is gone and I thoroughly enjoyed every moment of it. I spent a lot of time researching plenty of coke sites, so this is definitely going to be a very busy year. There's a lot left out there. Today I focused on some of these iron furnaces I was looking into and went to check them out. It was a great afternoon to spend in the mountains. The first three of these furnaces are located around New Florence and the last (and my personal favorite) is south of Laughlintown. Dates of construction range from 1810 to 1850 presumably, information on these sites is sketchy at best and it seems like nobody agrees on anything. The majority of the information I am using is from the 1966 book "A Guide To The Old Stone Blast Furnaces In Western Pennsylvania" by Myron B. Sharp and William H. Thomas. The two sites that have been restored have signs describing the history of the furnaces. For these sites I am using the information from the signs. I figure if they took the time and resources to restore these massive furnaces, they probably did a substantial amount of research on their history. 

 

 

Baldwin Furnace

 

The Baldwin Furnace is located in State Games Lands #42 in St. Clair Township. This is the earliest of the four. According to the book, Baldwin Furnace was constructed in 1810 by James Stewart and Henry Baldwin and was only in blast for a short time. It was a charcoal fueled furnace and I found slag laying around that still had charcoal and iron in it. That's it for information on this furnace.

 

 

A short walk up this road leads you to the furnace site.

Approaching Baldwin Furnace.

As you can see, the back side of it is in pretty bad shape.

Climbing down the hill to the furnace behind this retaining wall. I am assuming it's been rebuilt. The game commission keeps this area cleared of brush which is one of the main reasons this furnace is still standing.

The stonework is amazing.

Engravings in a tree from previous visitors.

Again. The stonework. I wasn't able to locate any mason marks in the stone and it's almost certain the names of the craftsmen are lost to time.

The other side of the furnace. This side also contains remnants of what could have been the race to turn the water wheel and operate the bellows to blast the furnace.

Possible race.

It heads down toward Baldwin Run.

More cut stone near what may have been the race.

Laurel Hill Furnace 

 

 

Laurel Hill Furnace is located close to Baldwin Furnace but it's off state game lands. It is located conveniently on Furnace Lane outside of New Florence. This is one of the furnaces that has been preserved and is currently under the supervision of the National Park Service. According to the book, this furnace was built during 1845-46 by Hezekiah Reed, Gallagher and Hale. It was later owned by Judge J.T. Hall of Centre County. This furnace operated until 1855.

The informational sign at the site. The information on this sign is identical to that in the book.

What I love about these furnaces is that they're all unique. They all served the same function but none of them look the same. Some have these massive arches and others have openings that come to points. The arches are 12 feet high. Another unique feature of this furnace is that all four sides have arches.

A look inside the front arch. Three iron bars support the structure.

Looking up the stack.

Slag coated on the brickwork of the stack.

I'm guessing this is the hole where the molten iron flowed from.

Inside the furnace.

This masonry work is still incredible but it's not as tight as Baldwin Furnace.

The arches on the other hand.....

The whole furnace is fastened together with these tie rods.

From inside the furnace. Probably where the molten iron flowed out.

Ross Furnace

 

 

This was the trickiest one to get to. It is located on a golf course in the Ross Mountain Club, a country club. I am not a country club kinda guy (picture Bill Murray in Caddyshack). The area is heavily posted with Members Only signs so I did the only thing a fella in my situation could do. I snuck in. It was successful, I got my photos and got out. According to the book, Ross Furnace was constructed in 1815 by James Paull, J.D. Mathiot and Isaac Meason. This furnace was in blast until at least 1850. Aside from making the usual pig iron, Ross Furnace also produced pig iron stoves, sugar kettles, pots, ovens, skillets etc.

Meason is a huge name in local industrial history. He was the first man to make a fortune west of the Alleghenies in the iron business. Most of his interests were in Dunbar, Fayette County including his Union Furnace on Dunbar Creek which was producing iron by 1791. By 1788 he owned thousands of acres of land and was the wealthiest man in Fayette County. 

 

 

 

It's a shame it's hidden on a golf course but they seem to be taking great care of it.

The inside of these arches is different from the others.

Looking up the stack. It's all cleaned up. It looks like it's coated with concrete.

More heavy iron supports.

This furnace has both arches and points. This is the back side facing the golf course.

Tight corners.

Incredible stonework.

California Furnace

 

 

This was my favorite location from today. The book says the furnace was constructed in 1853, the sign says 1850 and the 1994 inventory of historic engineering and industrial sites says 1852. What they all agree on is the furnace was built by Col. J.D. Mathiot and Dr. S.P. Cummings. This is the second time Mathiot has popped up but the first time he's listed as a Colonel. The furnace is located on the old Philadelphia and Pittsburgh Turnpike along Furnace Run. Furnace Run was known as California Run at the time. California Furnace was later sold to Alexander Cavat, who supposedly invested a fortune into it but didn't see a profitable return. The furnace went out of blast 1862. In 1966 Gen. Richard K. and Constance Prosser Mellon restored the furnace.

 

 

To get to California Furnace you get to cross this covered bridge.

It is called the Naugle Bridge. I haven't been able to find a construction date.

If you're too heavy, you have to go through the creek.

Furnace Run, Google Maps calls it Rolling Rock Creek.

California Furnace.

Incredible.

This ring is leaning against the back of the furnace.

This is on the left side of the furnace in an arch. Adjacent to this is the race where the water wheel went so this would probably be where the bellows blasted the furnace.

This is under a small plank bridge on the left side of the furnace.
