On a recent morning outside of Lake Placid, a team of researchers traded shovels for handheld tablets as they watched a drone lift off from a bright orange landing pad, tilting forward and beginning its programmed flight over a dense stretch of Adirondack forest.<\/p>\n
On the ground, Eileen Ernenwein and Steven Jones, geosciences professors from East Tennessee State University, monitored the drone\u2019s flight path. The aircraft, equipped with light detection and ranging, or LiDAR technology, soared about 325 feet overhead.<\/p>\n

The aircraft covered about 200 acres of woodland once believed to be part of Timbuctoo, a 19th-century Black settlement founded near Lake Placid by white abolitionist Gerrit Smith<\/a>. In the mid-1800s, Smith granted parcels of his vast Adirondack property to Black families, hoping land ownership would offer economic independence and, at the time, the right to vote.<\/p>\n But over time, the forest reclaimed much of that landscape. Homes, roads and farm fields faded from history, leaving only fragments in historical maps and in scattered archaeological evidence.<\/p>\n Now, researchers are turning to remote sensing technology to survey land once believed to be home to several Timbuctoo land grantees, hoping to find traces of human activity carved into the landscape nearly 200 years ago.<\/p>\n To do that, Ernenwein is using millions of data points collected by the LiDAR drone to build a detailed three-dimensional map of the forest floor.\u00a0<\/p>\n The drone\u2019s LiDAR sensor fires roughly 160,000 pulses of light every second. Those pulses bounce off the ground and return to the aircraft, where timing differences are calculated into elevation data. Ernenwein said even when dense trees shroud the ground, LiDAR can still get an accurate read of a landscape\u2019s subtle contours.<\/p>\n \u201cImagine you\u2019re walking in the forest on a sunny day, and there\u2019s trees overhead. You\u2019re in the shade, but there\u2019s little spots of sunlight getting filtered through,\u201d Ernenwein said. \u201cThat\u2019s the same way the LiDAR is getting in there. It\u2019s getting in between branches and leaves.\u201d<\/p>\n The result is a digital version of the forest floor stripped of vegetation, revealing contours that are otherwise impossible to see.<\/p>\n \u201cIt\u2019s a real needle in the haystack,\u201d she said. \u201cBecause if you just look in those woods, you see how rough the ground is. The ground is not flat.\u201d<\/p>\n New leads on Timbuctoo<\/p>\n The survey is part of a long-running effort led by Hadley Kruczek-Aaron, an anthropology and archaeology professor at SUNY Potsdam, who has studied Timbuctoo for more than 15 years. This latest research method is a collaboration between Kruczek-Aaron, East Tennessee State University and historians from Adirondack Experience, the Museum on Blue Mountain Lake.<\/p>\n Before LiDAR, Kruczek-Aaron surveyed the remote hillside with metal detectors, small excavations and days of hiking through uneven terrain in search of subtle clues. The drone, by comparison, mapped the entire 200-acre hillside in about 90 minutes.<\/p>\n \u201cIt\u2019s an incredible amount of land that they can cover in a short amount of time,\u201d said Kruczek-Aaron.<\/p>\n She said the early results are already pointing to subtle anomalies in the landscape\u2014shapes and contours that could signal past human activity.<\/p>\n \u201cOne of the things that we could potentially see are features that would be evidence of field clearing,\u201d she said. \u201cWhen [settlers] were dealing with the rocky Adirondack soils, they\u2019re going to be taking out as much stone as possible and piling it up.\u201d<\/p>\n Those piles of stone can sometimes appear in LiDAR imagery as faint lines or mounds, an indication that the land could have once been farmed.<\/p>\n \u201cThose are the kinds of things that might show up on those LiDAR results and help us hone in on an area,\u201d Kruczek-Aaron said.<\/p>\n One of the central goals of this surveying project is to pinpoint locations where Timbuctoo families actually lived and farmed.<\/p>\n When Timbuctoo land grantees originally settled on their parcels, New York State law required them to work the land and produce $250 to gain enfranchisement. The rugged mountain landscape and harsh weather forced some families to leave, making their stories more difficult to trace.<\/p>\n Kruczek-Aaron has focused much of her work on a few remaining historical threads. One of the best-documented is Lyman and Anna Epps\u2019 family, who moved from Troy with their two children and settled on the hillside around 1849.<\/p>\n \u201cThey developed a very viable farm,\u201d Kruczek-Aaron said. \u201cWe know that they are in this vicinity, and it\u2019s just about where exactly they are.\u201d<\/p>\n Living history<\/p>\n During the weeklong survey, Kruczek-Aaron walked the site with descendants of Timbuctoo settlers, pointing out areas where LiDAR data suggested further investigation.<\/p>\n Tanya Jones, who descends from Timbuctoo pioneers Phoebe and Edward Weeks, traveled from Massachusetts to see the work firsthand.<\/p>\n \u201cI think being here really kind of shows the challenge that they faced,\u201d she said. \u201cJust imagining people coming up here with an ox and a cart and maybe some axes to try to tame this space and make it a productive place to farm.\u201d<\/p>\n The history was already familiar to Jones. Her mother, Katherine Butler-Jones, conducted foundational research<\/a> that helped shape \u201cDreaming of Timbuctoo,\u201d<\/a> a permanent exhibition at John Brown Farm exploring Black settlement in the Adirondacks.<\/p>\n Standing on the hillside where those settlers once lived, Jones said the visit added a dimension in understanding her family\u2019s history in a way that maps and research cannot fully capture.<\/p>\n \u201cIt just deepens my respect for all of the pioneers in the Adirondacks,\u201d she said, \u201cparticularly the ones that came from urban New York with few means, most likely, to make a life.\u201d<\/p>\n So far, researchers say the LiDAR maps have identified around five small areas that may contain remnants of field systems, stone piles or building foundations. Those locations will guide future ground surveys and excavations as archaeologists continue working to match the digital landscape to what once stood on it.<\/p>\n![\"\"](\"https:\/\/www.newsbeep.com\/us-ny\/wp-content\/uploads\/2026\/05\/IMG_9813-1200x900.jpg\")
