The reverent quest to find the East Coast's most majestic trees

Working off tips from volunteers, two giant-hunters are tracking down the biggest, tallest, oldest trees in the eastern U.S., from sweetgums on Staten Island to white pines in the Adirondacks.

One of the largest Black Walnut trees in the United States.
After hearing about this Black Walnut tree (Juglans nigra) from two separate people, photographer Brian Kelley knew he had to see it for himself. "From a distance I could make out its massive limbs, though the base wasn’t completely clear," he says. "As I got closer, it became obvious that this walnut could be the largest of its species in New York State. Around the same time I was measuring the tree, the current National Champion had been taken down. With nothing else close to this one in total points, it may ultimately prove to be the largest Black Walnut in the United States." Location: Livingston County, New York. Circumference: 303”. Height: 101’. Average Crown Spread: 106’. Total: 430 points.

Brian Kelley and Erik Danielson are giant hunters. For almost a decade, they have scoured the country’s forests in pursuit of their quarry, parsing dense canopies with satellite photography and following rumors. They wake early and return to their campsites late, forgoing hot food and comfort while on the trail. Like seers, they follow their palms through the brush, moving in silence until they arrive at their prize: the East Coast’s biggest trees.

Since 2017, the pair have collaborated to photograph old-growth forests across the American East, from the fern-dotted gullies of the Adirondacks to the tangled swamps of North Carolina. Brian, a photographer, and Erik, a botanist, each bring a unique expertise to their craft, but are bonded by a bone-deep determination.

The largest Tulip tree in NYS.
Nicknamed the Clove Lake Colossus, this Tulip tree (Liriodendron tulipifera) is recognized as the largest of its kind in New York State. Though there are taller Tulip trees throughout the state, this tree's circumference gives it the points to take the title. Location: Richmond County, New York. Circumference: 288”. Height: 127’. Average Crown Spread: 89’. Total: 437 points.
The Bitternut Hickory shares the title as the largest of its species in NYS.
Hidden on an estate in Nassau County dating back to the 17th century, this Bitternut Hickory (Carya cordiformis) shares the title as the largest of its species in New York State. Location: Nassau County, New York. Circumference: 153”. Height: 106.5'. Average Crown Spread: 60’. Total: 274 points.

Brian first became interested in big-tree hunting through American Forests, a nonprofit that had catalogued significant specimens across the United States through the national Register of Champion Trees. The register started as a short list of 77 big trees featured in the April 1941 edition of American Forests magazine. By 2021, it had grown to 562 Champion Trees across the country. Since 2023, the program has been adopted by the University of Tennessee School of Natural Resources, but the full list of Champions is accessible through the National Champion Tree Program website, which features trees by state, the year nominated, and their accessibility to the public.

To qualify as a Champion, a tree must meet a specific threshold of “points,” determined by size and calculated by a mathematical formula: Trunk circumference (inches) + height (feet) + ¼ average crown spread (feet) = total points. The point system is species dependent. What is a remarkable score for an apple tree pales in comparison to the score for a giant sequoia, which is why the equation is an essential component of the qualification process. For example, in the Pacific Northwest, where a majority of the nation's champion trees reside, the point spread is higher only because of the species that dominate their older forests.

Many of these initial findings were sourced through the efforts of volunteers, “regular folk” as Brian put it—accountants, teachers, day hikers—anyone similarly entranced by the hunt. However, despite the program’s history and dedicated base of volunteers, there were very few high-quality photographs of these trees.

“The images listed online were always grainy or out of focus,” Brian explains. “It makes sense, most people aren’t trained in composition, or how to understand shifts in lighting. They weren't photographers, and that’s ok.”

This is now the largest known single-stem Sugar Maple in NYS and possible National Champion.
Photographer Brian Kelley drove past this tree several times but could never truly judge how big it was from his car. "I eventually got permission from the owner to measure the tree," he says. "He mentioned that he’d been wanting to have it measured for a while and said the circumference was close to 20 feet! He wasn’t wrong…" This specimen is now the largest known single-stem Sugar Maple (Acer saccharum) in New York State and a possible National Champion. Location: Duchess County, New York. Circumference: 231". Height: 94.1'. Average Crown Spread: 95’. Total: 348.75 points.
The “Big Foot” Pine, the world largest known Eastern White Pine by wood volume.
Behold the “Big Foot” Pine, the world largest known Eastern White Pine (Pinus strobus) by wood volume. Gathering Growth collaborator and naturalist Erik Danielson received a tip about an area of unusually tall pines in the Adirondacks. Historic records suggested the forest was remarkable in 1902 but presumed destroyed in a massive storm known as the Big Blowdown of 1950. LiDAR analysis, however, revealed hundreds of acres of tall trees where none were expected. During a July 2023 visit to explore the site, the search paid off with the discovery of this massive pine. The tree has sequestered an estimated 35.7 tons of CO₂ in its lifetime, roughly equivalent to the emissions from driving a typical car about 350,000 miles, and it stands among a broader forest of unusually large, old, and tall trees that somehow survived the devastating long-ago storm. Circumference: 196.7". Height: 151’ 6”. Average Crown Spread: 58.6’. Total: 362.8 points.
This tree is recognized as the largest Pin Oak in NYS.
This tree is recognized as the largest Pin Oak (Quercus palustris) in New York State. Also known as a Swamp Oak or a Swamp Spanish Oak, this cultivated tree has a known history dating back to plantings in or around 1880s. Location: Chautauqua County, New York. Circumference: 237”. Height: 102.7'. Average Crown Spread: 88.2’. Total: 361 points.

In 2016, Brian began building his own portfolio, first with his digital camera, then moving into large format photography. In 2019, he created Gathering Growth, a foundation that seeks to document trees of ecological, cultural, and historical significance across the East Coast—with or without a Champion designation. This departure from exclusively documenting Champion trees was driven by Brian and Erik’s belief that the definition excludes other remarkable specimens that fall short of the traditional point system. For example, the largest sweetgum by points in New York State is located on the historic Lyndhurst Estate, a pastoral property near Tarrytown. However, the tallest sweetgum in the state stands in a park on Staten Island, hidden in a scrap of forest surrounded by suburban neighborhoods. Unfortunately, most big trees are not so easily reached.

In order to sift through the acres of untrammeled wilderness where most of their finds are located, Brian and Erik rely on a blend of tips, decades-old surveyor maps, and cutting-edge technology. One tool that has become integral to their process is Light Detection and Ranging (LiDAR), an active remote sensing technology that uses laser pulses to create 3D representations of the Earth’s surface. This provides unique insight into the landscapes they venture into, which are often untrailed, uneven, and dense. Once a promising patch of forest is located, the next step is to reach it—which is easier said than done.

This Pitch Pine is thought to be one of the oldest known of its species in NYS.
This Pitch Pine (Pinus rigida) is thought to be one of the oldest known of its species in New York State. First discovered in the 1970s, it's now confirmed that the tree is 412 years old (going on 413 this year). It first started growing in the year 1613. Location: Ulster County, New York. Circumference: 47". Height: 20’ 3”. Average Crown Spread and Points unknown.
One of the largest known specimens of Pumpkin Ash in NYS.
This stunning tree is of the largest known specimens of Pumpkin Ash (Fraxinus profunda) in New York State. The New York Natural Heritage Program designates the Pumpkin ash with an S1 rank, indicating it typically has five or fewer statewide populations, and other factors that make it highly vulnerable. Location: Bronx County, New York. Circumference: 136”. Height: 92.75’. Average Crown Spread: 53.55'. Total: 242.13 points.
This is the New York State Champion White Ash, a tree that appeared almost dead upon my arrival to photograph it.
This New York State Champion White Ash (Fraxinus americana) first appeared almost dead when Brian Kelley arrived to photograph it. With the Emerald Ash Borer, an invasive beetle, devastating ash populations across the Northeast, "trees of this size are becoming increasingly rare," Kelley says. But luckily for this tree, it had simply dropped its leaves early. For the time being, it still holds the title of the largest known White Ash in the state. "But for how much longer ... who knows?" Location: Livingston County, New York. Circumference: 252”. Height: 101’. Average Crown Spread: 80’. Total: 373 points.

“These aren’t pleasant day hikes,” Brian explains. “It’s not unusual for us to arrive at dawn and not make it out of the woods until dusk. Time is our most valuable resource, and I never feel like we have enough of it. Sometimes I fall into a trance, and I’ll just go until my legs give out.”

Despite the literal blood and sweat that go into some of these trips, each tree is photographed with patience. It’s not unusual for Brian and Erik to spend hours with a single tree, only leaving once they feel they’ve done it justice. Oftentimes, they’ll return to the same tree again and again over the course of a year depending on its accessibility and health. “Bigfoot,” which is the largest white pine known in existence, was discovered in 2023 by Erik in a remote section of the Moose River Plains Forest of the Adirondacks. Since its discovery, the pair have journeyed back on several occasions to take photographs or show interested parties. For other trees, they will return to run checkups if they know it is in poor health, looking for blight, breakage, or simply to confirm it’s still standing.

“Some of these trees have spent hundreds of years growing,” Brian says. “The least I can do is spend an hour with them.”

Their forthcoming book, Gathering Growth, Vol. 1: NY, is an attempt to imbue readers with a similar sense of reverence for these remnants of ancient forest—not only for their scale and beauty, but for their cultural importance. In the foreword, Brian writes: “Before a landscape can be protected, it must be known. Before it can be known, it must be remembered. By presenting trees with the same rigor traditionally reserved for art objects, historical artifacts, or architectural landmarks, the project reframes old-growth and large trees as irreplaceable cultural assets, not merely biological resources. This shift in perception is essential: people protect what they recognize as meaningful.”

This Kentucky Coffeetree is recognized as the largest known of its species in NYS.
Kentucky Coffeetree (Gymnocladus dioicus), native to the Midwest, likely arrived in Central New York through Indigenous trade routes, where seeds were exchanged and dispersed along well-traveled paths. Over time, these trees became part of the region’s ecological history. This specimen is recognized as the largest known of its species in New York State. Location: Cayuga County, New York. Circumference: 204”. Height: 94’. Average Crown Spread: 60’. Total: 313 points.
This one of a few large Beech that we know of in NYS.
To see an American Beech (Fagus grandifolia) of this size is increasingly uncommon in the Northeast, Kelley notes, as Beech Bark Disease and Beech Leaf Disease continue to decimate populations across the region. This one of a few large Beech that conservationists know of in New York state. Location: Cayuga County, New York. Circumference: 145”. Height: 99.2’. Average Crown Spread: 76’. Total: 263.2 points.
The largest known Red Maple in New York State growing on an old upstate farm.
Currently recognized as the largest known Red Maple (Acer rubrum) in New York State, this tree grows on an old upstate farm where generations of children have played beneath its
canopy, watching it grow over the years. Location: Jefferson County, New York. Circumference: 231”. Height: 84.5’. Average Crown Spread: 77.3’. Total: 334.8 points.

This sense of meaning was made clear over Indigenous Peoples’ Day weekend in 2025, when a well-placed tip brought Brian and Erik to Stillwater Reservoir—a remote slice of water in the Five Ponds Wilderness of New York State. Brian had learned about the reservoir after giving a lecture to the New York Forest Owners Association in Albany. Just as he finished, an older gentleman beckoned to him. He told Brian about a section of forest that had never been logged. It was called Big Burnt Lake, and giants hid among its shores.

For months, Brian and Erik pored over surveyor maps and LiDAR scans to confirm the claim. One promising lump appeared in the satellite images, and they pinned its location. With their destination set, they made travel arrangements. It would take a two-hour drive, a three-mile canoe trip, and eight miles of bushwacking to reach their prize.

On the morning of the hunt, they met at the Stillwater Reservoir boat launch and loaded their canoe in the bony light, sharing few words. Both knew what lay ahead—the hours of searching, the anticipated ache in their legs and shoulders from hauling gear, the race against a setting sun—all made worth it by the moment of discovery. To stand before one of these trees can only be likened to setting foot in a grand cathedral. They are monolithic, almost unending, rising through the overstory with straight trunks that brush the sky.

With no wind, Brian and Erik glided across the water in sync with their reflections, all four of them shimmering as they headed into the wilderness to begin their work.

It was going to be a long day.
