You can't see any of the above rocks during the Oct 23, 2026, flood. Although some rocks are creating some "lumps" in the water.

Robert Holmes posted three photos with the comment: "🌊🌊Animas at the Swinging Bridge! It is running at 7700 cfs at 530am. Level 7.17. Just below flood stage. Flood stage predicted at approximately noon today. There will be another foot of river rise!"

We’ve been closed for the past couple of days, waiting for this storm to wear itself out, and will remain closed likely through Sunday, as we get everything resituated and put the shop back to rights.

The Animas River is reminding us just how feisty she can be, leaping past 10,000 CFS, up from the sad little trickle she was just a couple weeks ago- the majority of that in the last two days. She’s made her way up onto the trail by the next building north of us, and is lapping at the concrete near us, too, but so far, so good for the bookshop.Oh, the humbling power of fast-moving water! It’s a great reminder that Mother Nature is very much calling the shots, and we’re all just along for the ride.

A million thanks to the three fine gents who helped me batten down the hatches and who have been keeping watch over the place while (being the commuter that I am,) I can only keep an eye on things from afar. You guys are the best.

So, hooray for some much-needed moisture, a deep bow to the mighty Animas, and a gentle reminder that impermanence is the way of things. Sometimes the best we can do is prepare, let go, and ride out the storm.

We’ll be back before long, with books to browse, curiosities to discover, and plenty of stories waiting to be found.

Until then, stay safe, stay dry, and stay in utter awe of it all, friends. We'll be back soon!

"This classic Camelback through truss bridge has been rehabilitated for continued vehicular use."
The 200' (61m) long span is 15' (4.6m) wide.

The rehabilitated bridge has a weight limit of 13 ton. [BridgeHunter]

"This bridge is being torn down. What a shame, truly."

Jan 2, 2009 comment by Anthony Dillon in ArchivedBridgeHunter:

GOOD NEWS.........

This bridge is being disassembled-not for storage or relocation, but it is to be restored and reassembled in place.

Ohio has been doing that with some of their spans, but this might just be a first in Indiana (for a steel truss bridge).

Anthony provided several photos in the comments of the assembly of the bridge. The truss was reassembled on land. The wooden deck was added after the truss was lifted over the river. The original cut stone abutments were reused.

One advantage of the truss being assembled on land is that it is easier to get detail shots of the outside of the truss.

It is obvious that this is a three-hinged arch because the hinge at the crown is so explicit.

Our last shot from Monday's chase was our best, and a good way to end our long weekend in the Upper Peninsula. E&LS 400/600 crossing the Menominee River south of Iron Mountain with 35 cars of scrap from Alter Metal Recycling, which is located out of the frame to the left. Our long trip back to Duluth was made easier by listening to the Brewers beat the Dodgers. Kingsford, MI - October 12, 2026 Note: drone flight in restricted airspace was approved using LAANC.

Scott Best: Awesome! What's near by that area that makes the air space restricted!?

"The Historic American Engineering Record reported that the bridge is probably the second bridge at this location, since the Chicago, Milwaukee, and St. Paul Railroad reached Iron Mountain in 1886. A period article about the bridge stated that the previous bridge was a Pratt deck truss with a 225 foot span. A historical photo of the arch bridge under construction appears to show the previous bridge in the background as a double intersection Pratt (Whipple) deck truss."

I noticed that this 1910's bridge used riveted gusset plates rather than pin connections. Historic Bridges confirms that this would be an early example of riveted connections.

HistoricBridges
"This bridge was built by the Elkhart Bridge and Iron Company of Elkhart, Indiana, one of many medium-sized metal truss bridge companies in the Midwest during the late nineteenth and early twentieth centuries."
"Most through truss bridges that have this general appearance, with a traditional trapezoidal design and fairly lightweight members, have pinned connections, but this bridge has riveted connections instead."

Jennifer Woodman posted 13 photos with the comment: "The 22 1/2 Mile Road Bridge near Clarendon in Calhoun County, MI was built in 1906 by the Elkhart Bridge and Iron Company and is historically significant as the last remaining truss bridge in Michigan associated with them. The bridge is a six panel rivet-connected Pratt through truss with a wood deck. It was closed to traffic by 2011.— in Clarendon, Michigan."

2026 Ozinga Low-Carbon Slag Cement Mill in East Chicago, IN

(Satellite? I looked at a half-dozen web pages, but I could not find the location in East Chicago. It is too new to show up in a satellite image in Oct 2026.)

Ozinga posted

We have officially cut the ribbon on our new slag cement mill in East Chicago, Indiana! This is a proud milestone for our team, for Midwest construction, and for every project team working to reduce embodied carbon without giving up performance.

Slag is produced during steelmaking. Instead of letting it go to waste, we recycle it into high-performance slag cement. At full capacity, the mill will produce one million tons of slag cement every year.

The mill is projected to offset more than 700,000 metric tons of CO₂ annually, the equivalent of taking more than 150,000 gasoline-powered cars off the road for a year. Our CarbonSense blends deliver up to 80% less embodied carbon than traditional Portland cement mixes, and all products meet ASTM C989 and ASTM C1157 performance standards, giving designers and specifiers a compliant path to lower-carbon concrete. 

Supply constraints have led to allocations, delays, and price swings for Portland cement in recent years. Direct rail, water, and highway access lets us move material reliably across the Midwest and beyond. One barge carries the equivalent of 75 semi-trucks, which also lowers the total embodied carbon of every ton we ship.

"We built this mill in the heart of the Midwest because we believe it is central to producing high-performing, American-made materials that will be the foundation of U.S. infrastructure for years to come. We are taking the cement-to-concrete process from start to finish, with American ownership at every step of the domestic supply chain, with homegrown scientific innovation, and with American workers all the way." - Marty Ozinga 

We're grateful to Gov. Mike Braun, U.S. Sen. Todd Young, U.S. Rep. Frank J. Mrvan, East Chicago Mayor Anthony Copeland, the East Chicago City Council, Morrison Construction, and many other partners and vendors, for helping bring this vision to life.

Clarence Deckinga: Y didn’t they use slag years ago for cement has the slag changed recently.

Ima Psuedonym: Clarence Deckinga Slag has been around for decades. We started blending it with Portland cement back in the early 90’s when Cement companies started using waste products as fuel for the kilns. The waste fuel adversely affected the strength gain of the Portland. Ground Granulated Blast Furnace Slag has a high percentage of calcium silicates to interact with the Portland’s high percentage of calcium aluminates, resulting in better concrete.

Ozinga
North America’s Largest Low-Carbon Cement Mill

At the heart of the facility is the MVR5300-C6 vertical roller mill from Gebr. Pfeiffer, the largest of its kind in North America. With six independent rollers and unmatched throughput capacity, the mill maximizes energy efficiency while minimizing carbon emissions.

“This isn’t just a plant—it’s a technological milestone,” said Timothy Burden, President of Gebr. Pfeiffer Americas. “The MVR5300-C6 sets a new benchmark for sustainable cement production.”

The facility will produce ASTM C989-compliant low-carbon slag cement, as well as proprietary blends under Ozinga’s CarbonSense™ brand, meeting ASTM C1157 performance standards and delivering up to 80% reductions in embodied carbon. Once fully operational, the plant is projected to offset more than 700,000 metric tons of CO₂ emissions annually, a significant reduction in the carbon footprint of U.S. construction.

Ozinga’s leadership in sustainable building materials has been strengthened by partnerships with Meta, the University of Illinois Urbana-Champaign, and other industry leaders. These collaborations have yielded AI-optimized low-carbon concrete, used in Meta’s DeKalb, IL data center, and enabled a 64% reduction in embodied carbon at the award-winning Amazon Web Services New Carlisle, IN data center, setting a new industry benchmark.

As of the Oct 2026 ribbon cutting, Ozinga's location map doesn't mark the location.

Between Everett and Mount Dallas, there was a spur that rounded a 180-degree turn as it crossed the Raystown branch of the Juniata river to the south side. There it served the Earlston Furnace. 

This was called the Thropp bridge. 

built in 1884 by the Everett Iron Company.

The furnace went idle shortly after opening, but was put back into operation when the company was purchased by Joseph Thropp in 1889 and put into blast in 1890. The furnace was shut down in 1923, and the company went bankrupt in 1933. In June 1933, the plant was sold to the Bethlehem Steel Corporation, who began dismantling it in June of 1934.

This furnace was connected to the H&BTM using the Thropp Bridge. But it was also directly connected to the PRR too. Refer to the map and you can see the direct connection bypassing the Thropp Bridge.

Byron Smail: Earlston furnace was 1 of the 4 major latest and most modern iron furnaces in the Juniata Iron District.

PRR Bridge in Everett.

Thomas AndChristina Turner: The Pennsylvania Railroad Bridge once carried trains across the Raystown Branch of the Juniata River as part of the rail line running through Mt. Dallas en route to Bedford. After years of disuse, the bridge was dismantled in 1986. Though largely forgotten and now obscured by vegetation, a single stone abutment still stands on the south side of the river. While difficult to see from Route 30, this surviving remnant marks the spot where trains once crossed the river and serves as a quiet reminder of the area’s railroad heritage.

The Pennsylvania Railroad Bridge served a rairoadl crossing in the area. As shown in these photos, this important structure carried the PRR line over both the Lincoln Highway and the Raystown Branch of the Juniata River. More significantly, it functioned as the critical junction that directed trains either to the turntable or onward to Bedford, making it a key component of Everett’s rail network.

When they first converted from truss to girder spans, they used wood bents for the new piers.

I was confused because these maps show just the Pennsy bridge. The H&BTM bridge would be curve back East to head to the Earlston Blast Furnace.
