North Creek is quiet. It’s a tiny hamlet in the town of Johnsburg, tucked away in the rugged folds of the Adirondack Mountains. Most people drive through it on their way to Gore Mountain to ski. They see the shops, the vintage train station, and the Hudson River. What they usually miss is the ground beneath their tires. It’s red. Not just red—it's heavy, industrial, and surprisingly precious. When you talk about garnet mines North Creek NY, you aren't just talking about a local hobby or a tourist trap. You are talking about the Barton family, the largest almandine garnet deposit on the planet, and a 140-year-old mining legacy that basically changed how the world sands wood and polishes glass.
Honestly, it’s a bit of a geological fluke.
About a billion years ago, during the Grenville Orogeny, intense pressure and heat cooked the rock here. It turned ordinary minerals into massive, deep-red crystals. While most garnets found globally are tiny—think the size of a grain of sand—the ones in North Creek can get as big as a beach ball. Seriously. The "Gore Mountain Garnet" is famous in mineralogy circles for its size and its weird, black hornblende rims.
The Barton Legacy and Why It Isn’t Just Jewelry
Henry Hudson Barton didn’t care about necklaces. In the late 1870s, he was working in the sandpaper business in Philadelphia. Back then, they used crushed quartz, which was okay but dull. Barton heard rumors of "heavy red stones" up in the Adirondacks. He tested some. He found that garnet was significantly harder than quartz. But more importantly, it fractured into sharp, jagged edges that stayed sharp as they broke down.
He moved his entire operation to the top of Gore Mountain in 1878.
The Barton Mines Corporation is still running today. It’s one of the oldest family-owned mining companies in the United States. They eventually moved the primary industrial operations from the original Gore Mountain site to Ruby Mountain nearby, but the impact remains. If you’ve ever used high-quality sandpaper or seen a waterjet cutter slice through three inches of steel, there’s a massive chance that the abrasive came from North Creek.
Most people assume "mining" means dark tunnels and canary cages. Not here. These are open-pit mines. They carved the top off the mountain. It’s an amphitheater of garnet-flecked rock. The original site is now a historic landmark, and it’s one of the few places where you can actually walk onto a "world-class" mineral deposit without a hard hat and a blasting permit.
Visiting the Garnet Mines North Creek NY Today
If you want to see this stuff for yourself, you head to the Gore Mountain Mineral Shop or the nearby Garnet Mine Tours. It’s located about five miles up the mountain from the center of North Creek.

The experience is pretty tactile. You aren't just looking at rocks behind glass. You’re standing in a massive trench where the walls are studded with red crystals. The scale of the "Old Hoppers" mine is hard to grasp until you’re standing at the bottom looking up at the jagged terraces. It feels prehistoric.
The minerals here are Almandine garnets. On the Mohs scale of hardness, they sit around a 7.5 to 8. Diamonds are a 10. This makes them tough enough to grind metal but brittle enough to stay sharp. It’s a weird contradiction that makes them industrially perfect.
What You’ll Find at the Old Pit
When you visit the historical garnet mines North Creek NY, the first thing you notice is the weight. Garnet is dense. If you pick up a rock the size of a grapefruit from the mine floor, it’ll feel twice as heavy as a regular Adirondack granite stone.
The colors are wild.
- Deep Wine Red: This is the classic Barton garnet color.
- Black Hornblende: This is the "shell" that surrounds the garnets in the rock matrix.
- White Feldspar and Green Pyroxene: These create a crazy "Christmas Tree" rock pattern that locals call "Ledge Rock."
You can actually keep what you find, within reason. Most tours allow you to haul out a bag of rocks. It’s probably the only place in the Northeast where a kid can find a semi-precious gemstone within thirty seconds of getting out of a minivan.
The Science Most People Miss
There is a huge misconception that these garnets are "gem grade" for rings and earrings.
Kinda, but mostly no.

The North Creek garnets are heavily fractured. Because they formed under such intense tectonic pressure, they have internal cracks. If you try to cut a 10-carat faceted stone out of a North Creek garnet, it’ll usually shatter. This is why they are perfect for abrasives—they want to break into sharp pieces. However, occasionally, you find a "clear" nugget. When polished, these have a dark, moody red glow that looks like a drop of old Bordeaux wine.
The Barton family realized early on that the money wasn't in the jewelry store; it was in the workshop. They developed secret methods for heat-treating the garnet to make it even tougher. For a long time, North Creek was the primary source of garnet for the entire world’s supply of sandpaper. Even now, with massive mines in Australia and India, the North Creek "Gore Mountain" garnet is considered the gold standard for high-end wood finishing.
Why the North Creek Deposit is Unique
Geologically, this place shouldn't really exist. Usually, garnets grow in metamorphic rocks like schist. In North Creek, they are found in a rock called granulite.
Dr. William Kelly and other geologists from the New York State Museum have spent decades studying this. They found that the garnets grew to such massive sizes because the rock stayed at a specific temperature and pressure for a very, very long time. It allowed the crystals to "eat" the surrounding minerals and expand.
It’s a slow-motion explosion of crystal growth that happened 15 miles underground before the mountains were ever pushed up.
Practical Tips for Your Trip
Don't just show up in flip-flops. You are walking into an old quarry.
- Wear sturdy boots. The garnet ore is sharp. It’s literally designed to be an abrasive. It will shred thin sneakers.
- Bring a spray bottle. The garnets look like dull red lumps when they are dry and dusty. Spray them with a bit of water, and they pop with that deep "ruby" red color. It makes it way easier to find the good stuff.
- Check the weather. The mines are at a high elevation. It can be 10 degrees cooler up there than it is in the village of North Creek.
- Visit the North Creek Depot Museum first. It gives you the context of how the railroad was built specifically to haul this heavy ore down the mountain.
The road up to the mine is steep. It’s a winding Adirondack backroad that pushes your car’s cooling system. But once you get to the top, the view of the High Peaks is almost as good as the rocks themselves.

The Economic Heart of the Adirondacks
We often think of the Adirondacks as a wilderness—a place for hikers and loons. But North Creek is a working town. The garnet mines North Creek NY provided a middle-class life for generations of families when the logging industry started to fade.
The Barton family still employs a significant portion of the local population at their Ruby Mountain site. They are quiet about it. They don't run big flashy ads. They just keep grinding, literally.
This isn't just history; it's a living industry. When you stand in the old 1880s pit, you can hear the faint hum of the modern plant a few miles away. It’s a rare link between the 19th-century industrial revolution and 21st-century precision manufacturing.
Moving Beyond the Surface
If you’re looking for a deeper dive, check out the local "Garnet Studio." There are local artisans who have figured out how to work with the fractured nature of the stone. They create "Adirondack Ruby" jewelry by using lapidary techniques that stabilize the stone. It’s a great way to take a piece of the mountain home that isn't just a heavy rock in your trunk.
Also, keep an eye on the ground in the village. The town uses "tailings"—the leftover crushed rock from the mine—for everything. You'll see red garnet sand in the sidewalk cracks and used as decorative stone in flower beds. The town is literally stained red by its history.
Actionable Steps for Your Visit
If you're planning to explore the garnet mines North Creek NY, don't just wing it. Start by booking a tour at the Gore Mountain Garnet Mine (the historical site) to get into the actual trenches. It's usually open from July through Labor Day, with some weekends in the shoulder seasons.
After you’ve gathered your samples, take them down to the Mineral Shop to have them identified. They can tell you if you've found a rare "sunstar" garnet or just a high-quality piece of industrial ore. Finally, spend an hour at the North Creek Depot Museum. Seeing the old photos of men hauling these massive boulders by hand puts the whole "vacation activity" into perspective. It was back-breaking work that built this town.
Pack a pair of work gloves, grab a sturdy bucket, and don't forget to look up from the rocks occasionally—the view of the Hudson River valley from the mine site is one of the best-kept secrets in the park.
