**History**
The deep indigenous history of the land comprising [Blacklick Woods Metro Park](https://www.metroparks.net/parks-and-trails/blacklick-woods/) came to light in stages, beginning with a major discovery during the park's mid-century expansion. In 1961, the park district acquired a 100-acre parcel of land where a previous owner had stripped away topsoil and gravel from a five-acre section. Beneath the surface, workers uncovered 16 ancient fire rings buried roughly 30 inches underground. The park district promptly invited Dr. Raymond S. Baby, the respected Curator of Archaeology at the Ohio State Museum, to evaluate the site. After a thorough review, Dr. Baby confirmed the authenticity of the find and determined that the fire rings were the unmistakable remnants of a prehistoric Late Woodland period Indian village dating between AD 600 and AD 1200. This incredible area was proudly highlighted as the "Indian Village Site" on official Blacklick Woods park maps throughout the 1960s, anchoring the park's identity in Ohio's rich indigenous heritage.
Decades later, the park's archaeological timeline expanded significantly when a completely separate, grander feature was discovered hidden just west of Blacklick Creek. In 2017, David Lamp, an eagle-eyed former archaeologist from Lancaster, was systematically analyzing historical aerial photographs kept by the USDA to locate undocumented native structures. While examining a photograph captured in 1954 -- back when the property was still a rural farm owned by the Ashton Lamp family -- he spied a massive, distinct dark circle. Because perfect circles are an extreme anomaly in the natural world, Lamp immediately recognized the shadow as the footprint of a forgotten indigenous monument. Before the land became a protected park, decades of heavy agricultural plowing and livestock grazing had flattened the ground, wearing the structure's physical height down to an easily overlooked 10 inches tall.
To verify Lamp's incredible aerial find, a team from the Heartland Earthworks Conservancy partnered with park staff to clear away dense brush and trees covering the site. Renowned volunteer archaeologist Jarrod Burks led a sophisticated geophysical survey on September 24, 2017, inviting the public to watch the science unfold in real time. Burks pulled an array of highly sensitive magnetometers across the soil, measuring minuscule variations in the ground's magnetic content. Because topsoil holds a higher magnetic signature than deeper substrate layers, the instruments clearly mapped a massive, ancient ditch that had filled with topsoil over centuries of erosion. This advanced technology produced a stunning, flawless digital visualization of a hidden prehistoric circular earthwork buried right beneath the feet of unsuspecting park hikers.
The data collected by Burks revealed that the Blacklick Circle originally featured a three-to-five-foot earthen embankment pairing with a distinct interior ditch. The structure is estimated to have a total diameter of just under 100 feet, and the magnetic imaging perfectly captured the precise location of the circle’s original eastern entranceway. Archaeologists attribute this monumental construction to the ancient Adena or Hopewell cultures, pushing the park’s human history back roughly 2,000 to 2,200 years. While the Adena and Hopewell peoples are famous throughout the Ohio River valley for building giant burial mounds, circular enclosures like this one served distinct communal purposes. Because these earthworks do not contain human remains, they are understood to be highly sacred, carefully engineered gathering spaces for spiritual ceremonies and social alignment.
Today, the Columbus and Franklin County Metro Parks system treats this miraculous discovery as a crown jewel of regional cultural heritage. Rather than excavating and disrupting the sacred ground, the park utilizes a creative technique known as interpretive mowing. By cutting the grass at strategic heights, rangers visually outline the exact contours and entrance of the ancient circle so visitors can appreciate its scale from the adjacent recreational trail. Educational signs and informative placards now stand near the site, teaching families about the advanced architectural and mathematical skills of the region's first inhabitants. The discovery stands as a powerful reminder that our local green spaces are not just nature preserves, but deeply sacred, historical landscapes that have drawn human communities together for millennia.

**Summary**
For this event, we will hike about 4.5 miles by doing a couple loops of the Buttonbush, Tucker, Maple Loop, and Beech trails. Blacklick Woods is a very nice park, but it is generally flat and not strenuous, so this will be one of our easier hikes.
**Where We'll Meet**
Drive all the way to the back of the park to the parking lot that is nearest the Nature Center. There are restrooms here next to the [Canopy Walk](https://www.metroparks.net/parks-and-trails/blacklick-woods/#canopy-walk). We'll meet near these restrooms.
**After the Hike**
Afterward, we'll head over to [Eastside Brewing Co](https://www.eastsidebrewingco.com/) for drinks and [food](https://www.facebook.com/p/Smash-N-Eatz-61578406199442/). The actual address of the brewery is [1421 Davidson Dr, Reynoldsburg, OH 43068](https://www.google.com/maps/place/1421+Davidson+Dr,+Reynoldsburg,+OH+43068/@39.9541807,-82.8056303,17z/data=!3m1!4b1!4m6!3m5!1s0x8838648e132b4655:0x9d9c1d48e854e09b!8m2!3d39.9541807!4d-82.8056303!16s%2Fg%2F11bw49sw7m?entry=ttu&g_ep=EgoyMDI2MDkxMy4wIKXMDSoASAFQAw%3D%3D). We should be there by 5 if you can't make the hike and just want to join us for drinks.
