You’re driving through the Adirondacks, past the kitschy North Creek storefronts and the looming ski runs of Gore Mountain, and you see it. A sign for the Barton Garnet Mines. Or maybe you've heard about the Gore Mountain Gem and Mineral shop. People think it's just another roadside tourist trap where you pay ten bucks to sift through salted dirt for a plastic "emerald." It isn't.
This place is weird. In a geological sense, it shouldn't really exist the way it does. We’re talking about the world’s largest garnets. Not just little pebbles you find in a ring, but massive, basketball-sized deep red crystals embedded in dark rock.
Honestly, it’s one of the few places in New York where you can stand on a literal mountain of gemstones and realize that the ground beneath your feet is technically a global anomaly.
The Barton Family and the 1878 Discovery
History usually gets smoothed over by marketing, but the story of the Gore Mountain Gem and Mineral scene starts with Henry Hudson Barton. He wasn't some mystical mineralogist. He was a guy in Philadelphia who worked in the abrasives industry. He heard rumors about these giant garnets in the Adirondacks and realized something crucial: these weren't just pretty stones. They were incredibly hard and broke with sharp edges.
Barton moved up there in the late 1800s. He started a mining operation that stayed in the family for over a century. If you go to the site of the old Barton Mine today—which is often what people are looking for when they search for Gore Mountain minerals—you're looking at a legacy that basically powered the sandpaper industry for decades.
The garnet found here is a specific type called Almandine. It's got a chemical formula of $Fe_{3}Al_{2}(SiO_{4})_{3}$. But what makes the Gore Mountain variety special isn't just the chemistry; it's the size. We are talking about crystals that reached three feet in diameter. Most garnets in the world are microscopic or maybe the size of a pea. Here? They’re monsters.
Why are they so big?
Geologists are still arguing about this, which is the fun part. The leading theory involves a "metamorphic event" about a billion years ago. The rock around the garnet—mostly hornblende and plagioclase—provided the perfect "pressure cooker" environment. It stayed hot enough for long enough that the crystals had time to grow without being crushed or melted back into the earth's mantle.

Basically, the Earth took its sweet time with Gore Mountain. It didn't rush the process.
Visiting the Shop vs. The Mine Site
There’s often a bit of confusion when tourists head toward North Creek. You have the Gore Mountain Gem and Mineral shop, and then you have the Barton Garnet Mine tours. They are connected by geography but offer different vibes.
If you’re at the shop, you’re looking at a curated collection. It’s a place for collectors to find specimens that have already been cleaned and prepped. You'll see "Adirondack Ruby," which is just a fancy local name for the deep red garnet. Is it a ruby? No. Is it beautiful? Absolutely.
The real magic, though, is getting your hands dirty.
The old mining site, located at an elevation of about 1,900 feet, is where the scale of the operation hits you. It’s an open-pit mine. Most mines are dark, cramped holes in the ground. This is a massive, tiered amphitheater of rock. The walls are literally speckled with dark red spots. It looks like the mountain has chickenpox, but the spots are gemstones.
The "Sanding" Secret Nobody Tells You
Most people think of gems as jewelry. But the Gore Mountain Gem and Mineral history is actually a story of industrial grit. Until the mid-20th century, if you used high-quality sandpaper or were polishing glass for a telescope, there was a high chance you were using Adirondack garnets.

The crystals have a "conchoidal fracture." This means when they break, they create razor-sharp, curved edges. Even as the sandpaper wears down, the garnet keeps fracturing into new sharp edges. It’s self-sharpening.
That’s why the mine was so profitable. It wasn't about the jewelry market. It was about the fact that this specific rock was better at grinding metal and wood than almost anything else on the planet.
What to Look For When You Go
If you’re planning a trip, don't just grab the first red rock you see. Most of what’s on the surface has been weathered by New York’s brutal winters. It’ll look like a dull, brownish-red lump.
To find the good stuff, you need to look for the "matrix." That’s the black hornblende rock that surrounds the gem. If you find a piece where the garnet is still nestled inside that black shell, you’ve found a display piece.
- Color: Look for a deep, blood-red hue. If it’s too orange, it might be a different mineral or heavily weathered.
- Clarity: Realistically, you aren't finding many "gem-quality" clear stones here. These are industrial-grade garnets. They are opaque, beautiful, and heavy.
- The Crystal Face: Look for the "dodecahedron" shape. Garnets naturally want to form 12-sided crystals. Finding a piece that shows those flat faces is the gold standard for amateur collectors.
The Local Culture and the "Ruby" Myth
North Creek, the town right at the base of the mountain, treats garnet like its lifeblood. You'll see it everywhere. It's in the pavement, it's in the walls of the local bank, and it's definitely in every gift shop.
There's a local legend—sort of a tall tale—that the garnets were once so plentiful you could just scoop them out of the stream beds like gravel. While that might have been true in 1880, today it takes a bit more effort. But the "ruby" nickname persists.

Don't get scammed. If someone tries to sell you an Adirondack "ruby" for the price of a real Burmese ruby, walk away. You’re buying a garnet. It’s the New York State Gemstone, and it’s precious in its own right, but it’s a different mineral family entirely.
Logistical Reality Check
Don't just show up in flip-flops.
Gore Mountain is rugged. Even the "easy" paths at the mineral sites are full of sharp rocks. These are garnets, remember? They were literally mined to be used as abrasives. They will shred a pair of cheap sneakers if you aren't careful.
Also, the weather up there is temperamental. You can be in a t-shirt at the bottom of the mountain and be shivering in a rainstorm ten minutes later at the mine site.
If you’re heading to the Gore Mountain Gem and Mineral shop, it’s usually open seasonally. Most of the Adirondack tourist economy breathes with the seasons. Summer and "leaf-peeping" autumn are the peak times. In the winter, the focus shifts entirely to skiing, and the rocks are buried under six feet of snow.
Why Gore Mountain Still Matters
In an era of lab-grown diamonds and synthetic everything, there is something grounding about Gore Mountain. You’re touching a billion years of history. You’re seeing a mineral that helped build the American industrial revolution.
It’s not just about the "find." It’s about the context. Standing in a pit where 150 years of miners pulled stones out of the earth gives you a perspective on time that a jewelry store just can't provide.
The Gore Mountain Gem and Mineral experience is basically a geology lesson disguised as a scavenger hunt.
Actionable Steps for Your Visit
- Check the Calendar: Most Adirondack mineral sites and tours operate from late June through mid-October. Don't waste a drive in May; the ground is often still a mud pit from "mud season."
- Bring a Spray Bottle: This is a pro tip. Garnets look like regular rocks when they're dry and dusty. Spritz them with a little water and the red "pops," making them much easier to spot in the tailings.
- Invest in a Loupe: A small 10x jeweler’s loupe costs about fifteen dollars. Looking at a Gore Mountain garnet under magnification reveals a universe of fractures and inclusions that you can't see with the naked eye.
- Visit the North Creek Mosaic Project: After you've looked at the raw stones, go into town and see the 180-foot long mosaic wall. It uses local garnet and glass to tell the story of the area. It's the best way to see the "finished product" of the local mineral culture.
- Respect the Land: Don't trespass on active mining claims. The Barton company still operates a modern mine nearby (the Ruby Mountain mine). Stick to the designated tourist and rock-hounding areas to avoid a very awkward conversation with a site foreman.
