Most people driving over the 15th Street Bridge in Great Falls, Montana, don't even look down. Why would they? It's just a slab of rock and scrub in the middle of the Missouri River. But if you're a local—or a history nerd who has spent too much time digging through the archives of the Great Falls Tribune—you know that Black Eagle Memorial Island is a lot more than just a bit of land that survived a flood. It is a physical embodiment of the city’s industrial backbone, a quiet nod to the men who built the "Electric City," and a place that almost didn't exist anymore.
It’s weirdly beautiful in a rugged, industrial sort of way.

Honestly, the island is basically a ghost of the old Black Eagle Dam and Smelter era. Back in the day, this area was the literal engine of Montana's economy. The Anaconda Copper Mining Company didn't just operate here; they dominated the landscape. While tourists usually flock to the Giant Springs State Park or the C.M. Russell Museum, the Black Eagle Memorial Island offers a different kind of vibe. It’s for the person who wants to see where the raw power of the Missouri River was first harnessed for the massive copper smelting operations that defined the early 20th century.
What Actually Happened to Black Eagle Memorial Island?
There’s this common misconception that the island was always a memorial. It wasn't. For decades, it was just a piece of the industrial puzzle. The real shift happened when the old dam was replaced. When PPL Montana (and later NorthWestern Energy) took over the management of the hydroelectric facilities, there was a massive push to acknowledge the human cost and the human effort behind these structures.
The island itself is technically situated right below the Black Eagle Dam.
If you walk out there today, you’ll see the Black Eagle Falls Memorial, which was dedicated to the workers of the Anaconda Copper Mining Company. We are talking about thousands of men who labored in the shadow of the "Big Stack"—that massive 506-foot chimney that used to be the tallest in the world before they blew it up in 1982. The island serves as a permanent anchor for that memory. It’s a place where the industrial history of the Missouri River meets the modern push for public recreation and historical preservation.
The 1908 Flood and the Island’s Resilience
You can't talk about this island without talking about the flood of 1908. It was legendary. The Missouri River turned into a monster. It wiped out bridges, flooded the lower parts of the city, and threatened the very foundations of the original Black Eagle Dam. Yet, the rocky outcrops that form the basis of what we now call Black Eagle Memorial Island held firm.
Engineers at the time were stunned. The river was moving at a terrifying volume—some estimates suggest over 100,000 cubic feet per second—and yet the core geography of the falls remained. This resilience is why the island was eventually chosen as the site for a memorial. It represents the "unshakeable" nature of the workforce that built Great Falls.

The island provides a vantage point that is almost entirely unique. From the memorial site, you are looking directly up at the spillway of the dam. When the water is high in late spring, the sound is absolutely deafening. It’s not the serene, babbling-brook sound you get at a mountain lake. It’s a low-frequency rumble that you feel in your chest. It reminds you that even though we’ve "tamed" the river with concrete and turbines, the Missouri is still a force of nature.
- The NorthWestern Energy Connection: The island is part of the broader Missouri River Heritage Trail system.
- Accessibility: You can get there via the River’s Edge Trail, which is honestly the best thing Great Falls has going for it.
- The Memorial Plaque: Look for the specific markers that list the dates of the dam's reconstruction.
People often ask if you can fish off the island. Technically, yes, but the currents around the dam are notoriously "fickle." You’ve got to be careful. The water levels can shift based on power generation needs, so one minute you’re on a dry rock and the next, the Missouri is claiming its territory back.
Why "Memorial" Isn't Just a Fancy Name
There is a specific gravitas to this spot. In the early 1900s, working at the smelter was dangerous, back-breaking work. The Black Eagle Memorial Island is one of the few places in the city that explicitly honors that labor. While the rest of the world moved on to digital tech and service economies, this island stands as a reminder of when Montana was about copper, smoke, and sweat.
The memorial itself was a collaborative effort. It wasn't just a corporate PR move. Local historians and former smelter workers pushed for a place where their legacy wouldn't be washed away by time. When you stand on the island, you’re standing near the site of the first hydroelectric dam built in Montana (completed in 1890). That’s a big deal. That power didn’t just light up homes; it powered the mines in Butte and the refineries in Great Falls, creating a circuit of industry that made Montana a global player in the copper market.
Realities of Visiting Today
Let’s be real: it’s not a theme park. There are no gift shops on Black Eagle Memorial Island. It is a place of reflection. You’ll see joggers from the River’s Edge Trail pausing to catch their breath. You’ll see eagles—actual Black Eagles were the namesake, though they were likely Ospreys or Golden Eagles depending on who you ask—circling the thermals above the dam.
One thing that surprises people is how "industrial" the island still feels. You are surrounded by power lines, concrete structures, and the mechanical hum of the dam. Some people find that off-putting. Personally? I think it makes the memorial more authentic. It’s not a sanitized version of history. It’s history in the middle of a working power plant.
Mapping the Experience: How to Get There Without Getting Lost
Great Falls has a weird layout if you aren't used to the "numbered streets vs. numbered avenues" system. To get to Black Eagle Memorial Island, you’re looking for the northern end of the 15th Street Bridge.
- Park at the Black Eagle Trailhead: This is the easiest way. There’s a decent parking lot right off River Drive North.
- Hit the River’s Edge Trail: Follow the paved path toward the falls.
- The Pedestrian Bridge: There is a dedicated pedestrian bridge that takes you over the smaller channels of the river and onto the island proper.
- Timing: Go at sunset. The way the light hits the spray from the dam makes the whole island look like it’s glowing.
Most people spend about thirty minutes here. It’s a short stop, but it’s a dense one in terms of historical value. If you’re doing the full Lewis and Clark tour of the area, this is a necessary "industrial" bookend to the "wilderness" story usually told at the Interpretive Center further down the river.
The Environmental Turnaround
It’s worth noting that this area wasn't always "clean." For a long time, the stretch of river around Black Eagle Memorial Island was heavily impacted by the smelter’s runoff. We are talking about decades of heavy metals and industrial waste.
However, the cleanup efforts over the last 30 years have been nothing short of miraculous. The fact that the island is now a destination for birdwatchers and families is a testament to the remediation work done by the EPA and state agencies. It’s a "recovery landscape." You’re seeing a place that was once sacrificed for the economy being reclaimed for the community. That adds a whole other layer to the "Memorial" aspect—it’s a memorial to a damaged environment that is finally healing.
Expert Insight: The Engineering Feat
According to archival records from the Montana Power Company (the predecessor to the current utility owners), the Black Eagle site was chosen because of the natural 26-foot drop of the falls. This wasn't just luck; it was a geological gift. The island sits on a bedrock of Kootenai Formation sandstone. This stuff is incredibly tough, which is why the island hasn't eroded away despite the Missouri River’s best efforts over the last ten thousand years.
Common Misunderstandings About the Island
I’ve heard people say the island is private property. It’s not. While NorthWestern Energy manages the dam and the surrounding infrastructure, the island and the trails are open to the public. You don't need a permit to go out there and pay your respects or take photos.
Another weird rumor is that there are "tunnels" leading from the island to the old smelter site. While the smelter had an extensive underground flue system (some of which still exists in the hills of Black Eagle), there are no secret tunnels under the river to the island. It’s a cool thought, but it’s just local urban legend. The island is exactly what it looks like: a high point in the riverbed that was reinforced to serve as a bridge support and a commemorative site.
What to Look for Nearby
If you’ve made the trip to the island, don’t just leave.
- The Black Eagle Community: Head up the hill into the town of Black Eagle itself. It has a distinct "company town" feel and some of the best Italian food in Montana (looking at you, Borrie's).
- The Overlook: There is a park on the cliffs above the island that gives you a "drone-eye view" without needing a drone.
- The Big Stack Base: You can still see where the giant chimney once stood, though the area is mostly restricted.
How to Make the Most of Your Visit
If you're planning a trip to Black Eagle Memorial Island, don't just treat it as a checkbox on a list.

Bring binoculars. The bird life here is actually insane. Because the dam keeps the water from freezing completely in certain spots, you’ll see waterfowl here in the dead of winter when everything else is iced over.
Read the plaques. Seriously. I know most people skip them, but the names on those memorials are the surnames of the people who still live in the neighborhood. It’s a living history.
Respect the boundaries. The fences around the dam are there for a reason. The Missouri River doesn't care about your "perfect shot" for social media. Stay on the designated paths on the island. The currents near the turbine intakes are incredibly dangerous, and the water levels can rise in a matter of minutes if the dam gates are adjusted.
Final Takeaway on Black Eagle Memorial Island
Ultimately, this island is a bridge. Not just a physical one, but a bridge between the Montana of the past—one of extraction and industry—and the Montana of the future—one of recreation and preservation. It is a small, rocky piece of land that carries a massive amount of weight. Whether you're there for the history, the engineering, or just a quiet place to watch the river, it’s a spot that demands a little bit of your time and a lot of your respect.
Next Steps for Your Visit:
- Check the Flow: Look at the USGS water data for the Missouri River at Great Falls before you go; a higher flow makes the experience much more dramatic.
- Combine the Trip: Plan your visit as part of a 5-mile loop on the River’s Edge Trail, starting at the 1st Ave N bridge and heading east.
- Local History: Spend 20 minutes at the High Plains Heritage Center nearby to put the industrial context of the island into perspective before you step foot on it.
