History is messy. Most people think of "Big Tree New York" as just a point on a map or a generic landmark near Geneseo, but it’s actually a collision of natural wonder and a pretty tense diplomatic history that changed the shape of the Empire State. If you go looking for it today, you won't find a towering oak. It’s gone. It fell a long time ago.
The story is about a literal tree, yeah, but it’s also about the Treaty of Big Tree. That 1797 deal basically stripped the Seneca Nation of almost all their land in Western New York. It's a heavy legacy for a piece of timber.
The Giant That Was Big Tree New York
It was huge. Honestly, the measurements we have from the 18th and 19th centuries are staggering. This was a White Oak (Quercus alba) that stood on the fertile floodplains of the Genesee River. Some accounts from the Wadsworth family—the local land barons who ended up owning the property—suggested the trunk was nearly 27 feet in circumference. Imagine that. You’d need a small crowd of people holding hands just to circle the base.
People traveled miles to see it. It wasn't just a tree; it was a landmark for the Seneca people long before European settlers showed up with their surveying chains and inkwells. They called the area Ga-on-do-wan-nah, which translates roughly to "Big Tree." It served as a natural cathedral, a meeting place where the shade was thick enough to host hundreds of people at once.
Why it actually fell
Nature doesn't care about history. By the mid-1800s, the Genesee River started doing what rivers do—eroding its banks. The Big Tree stood right on the edge of a high bank. Even though the Wadsworths tried to save it by building a sort of breakwater or bulkhead, a massive flood in 1857 finally did it in. The ground just gave way. It didn't rot or get cut down for lumber; it simply lost its grip on the earth.

The 1797 Treaty of Big Tree: The Real Legacy
You can’t talk about Big Tree New York without talking about the land grab. This is where things get complicated and, frankly, a bit shady. Robert Morris—the guy who helped fund the American Revolution—had bought the preemptive rights to millions of acres in Western New York but he was broke. He needed to clear the "Indian title" to the land so he could sell it to the Holland Land Company and stay out of debtors' prison.
He sent his son, Thomas Morris, to negotiate with the Seneca.
The meeting happened in August and September of 1797 under the shade of that massive oak and some temporary wooden sheds. It wasn't a fair fight. The Seneca leaders, including Red Jacket and Cornplanter, were initially dead-set against selling. Red Jacket famously argued that they shouldn't sell the land that held the bones of their ancestors.
The Tactics Used
How do you convince a nation to give up 3.2 million acres? You don't do it with a fair handshake. Morris used a mix of:

- Direct Bribery: Giving individual annuities and cash to key influencers.
- Liquor: It’s a dark part of the record, but alcohol was used heavily during the weeks of negotiation to wear down the opposition.
- Side Deals: Targeting the women of the tribe, who traditionally held significant power over land decisions in Iroquois society, by promising them specific goods and influence.
By the time the ink was dry, the Seneca were left with just a handful of reservations (like Allegany, Cattaraugus, and Tonawanda) and $100,000 invested in the Bank of the United States. Basically, they lost everything west of the Genesee River for a pittance. When you visit Geneseo now, you’re walking on the site of one of the most consequential real estate deals in American history.
What’s left of Big Tree New York today?
The original tree is long dead, but its DNA (literally and figuratively) is still around. After it fell in 1857, people scrambled for souvenirs. You’ve got to remember, people back then were obsessed with relics.
- The Genesee Valley Museum and local historical societies hold various "sections" of the wood.
- The Big Tree Inn in Geneseo keeps the name alive, and it’s a staple for anyone visiting SUNY Geneseo.
- A "scion" or descendant tree was reportedly planted or identified from the original, though the lineage of these things is always a bit murky after 150 years.
If you drive down Route 63 today, the landscape still looks somewhat like it did—rolling hills, deep river silt, and massive oaks dotting the fields. The Wadsworth family still owns a significant amount of land in the area, and they've actually been pretty good stewards of the remaining old-growth oaks. They have a tradition of leaving the "mowing" around the big trees to let them thrive.
Misconceptions about the Location
A lot of tourists get confused. They look for a park called "Big Tree." It doesn't exist as a state park. The actual site where the treaty was signed is on private property, specifically the homestead of the Wadsworths. You can see the general area from the Geneseo overlook near the Main Street gazebo. It’s that vast, flat plain below the hill where the river snakes through.

People also confuse it with the "Big Tree" in other states. New York isn't the only place with a famous oak. But in terms of historical impact, this specific New York white oak holds a much heavier weight because of the treaty. It wasn't just a biological specimen; it was a witness to the end of an era for the Haudenosaunee Confederacy.
Expert Insights: Why the White Oak?
White oaks are survivors. They have this incredible ability to live for 400 to 600 years if the soil is right. The Genesee Valley has some of the most nutrient-dense soil in the Northeast thanks to thousands of years of river flooding.
Ecologists who study the region note that the "Big Tree" wasn't a fluke. It was part of an "Oak Opening" or a savanna-like landscape that the Seneca managed with controlled burns. They didn't just stumble upon a big tree; they helped create the environment where a tree could grow that large without being crowded out by smaller brush.
Actionable Steps for Visiting the Region
If you're heading to Livingston County to find the spirit of Big Tree New York, don't just look for a stump. You'll be disappointed. Instead, do this:
- Visit the Livingston County Historical Society Museum: They have actual fragments of the tree and the most accurate maps of where the treaty sheds stood.
- Walk the Geneseo Main Street: Look west from the wall near the bear fountain. That view of the valley is largely unchanged in its topography since 1797.
- Check out Letchworth State Park: It’s only about 15 minutes away. While it’s famous for waterfalls, the arboretum there gives you a sense of what the massive virgin forests of New York looked like before the 19th-century logging boom.
- Read the Treaty Text: You can find the 1797 Treaty of Big Tree in the National Archives. Reading the actual names of the Seneca signers—men like Young King and Handsome Lake—makes the history feel less like a textbook and more like a tragedy.
The story of Big Tree New York is really a story about how we value things. To the Seneca, it was a sacred center. To the speculators, it was a convenient landmark for a land grab. To us today, it's a reminder that even the biggest things—whether they are giant oaks or vast nations—can be uprooted by the slow erosion of time and the sharp edge of a pen. It’s worth the trip just to stand on that hill and think about what’s no longer there.
