Uncharted Lancaster

This episode explores the extraordinary life of Susanna Wright, an 18th-century polymath born on August 4, 1697, who emerged as one of the most remarkable—and overlooked—figures in colonial Pennsylvania. A Quaker intellectual of immense range, Wright was a scientist, poet, translator, and business owner who helped launch the region’s first silk industry while also providing legal and medical assistance to neighbor...

In this episode, we explore the brief but transformative canal boom that reshaped early America. From the Erie Canal and Pennsylvania's vast canal network to the Chesapeake and Delaware Canal, we examine how these ambitious engineering projects connected isolated farms to distant markets, fueled the Industrial Revolution, and forever altered the nation's economy and landscape.

The episode also traces the rapid decline of the canals ...

In this episode, we explore the First National Bank of Columbia, Pennsylvania, a remarkable building that began as an 1814 Federal-style mansion, evolved into a hotel, and eventually became a bank operating out of its front rooms.

In this episode, we explore the Good Shepherd Fireplace at Lancaster Theological Seminary, an extraordinary work of art hidden in the basement of Richards Hall. What seems at first like an unusual ceramic hearth in a dormitory lounge becomes a gateway into much larger stories involving the seminary’s long history of adaptation, the anti-industrial vision of artist Henry Chapman Mercer, and the ancient Christian imagery of the...

In this episode, we explore the extraordinary story of Theodore Burr’s 1815 bridge at McCall’s Ferry, a wooden engineering marvel that attempted to span one of the most dangerous crossings on the lower Susquehanna River. The transcript follows how Burr defied expert warnings, brutal winter conditions, and the violent hydrology of the gorge to build what was then the longest single wooden covered span in the world.

In this episode, we explore the strange collapse of Marietta’s early boom economy and the mystery of the 1823 robbery at the Marietta and Susquehanna Trading Company. What begins as a story of wild land speculation and a failed local bank turns into something far more unsettling: a heist in which the most valuable thing stolen was not cash, but the ledgers, notes, and legal records that proved who owed what.

In this episode, we explore the Hessian Ditch at Elizabeth Furnace in Lancaster County, Pennsylvania, a remarkable hand-dug canal carved through stone during the Revolutionary War by captured German soldiers. The story connects geology, ironmaking, and wartime necessity, showing how the ditch was built to divert water and power the furnace that supplied the Continental Army with munitions. 

Along the way, the episode traces the...

On June 28, 1863, Lancaster County was saved by fire.

The Columbia–Wrightsville Covered Bridge—once the longest covered bridge in the world—spanned the Susquehanna as the only crossing between Harrisburg and Maryland. When Confederate troops reached Wrightsville during the Gettysburg Campaign, Union militia made a desperate decision: burn the bridge rather than let the enemy cross.

In just hours, a mile-long wooden ...

In this episode, we step into the sweltering summer of 1744, when the small frontier town of Lancaster, Pennsylvania became the setting for one of the most consequential diplomatic gatherings in early American history. The Treaty of Lancaster brought together leaders of the Haudenosaunee Confederacy and representatives from Pennsylvania, Maryland, and Virginia for two tense weeks of negotiation over land, empire, trade, and surviva...

In this episode, we explore the rise and collapse of the Conestoga Navigation Company, the ambitious 19th-century effort to turn the shallow Conestoga River into a commercial water highway for Lancaster. The story follows the burst of canal fever that drove local leaders to invest in dams, locks, and slackwater engineering, transforming the river into a navigable route that briefly reshaped the region’s economy and linked Lan...

In this episode, we follow the desperate September 1777 flight of the Continental Congress as the British captured Philadelphia and the American government was forced to run for its life.

In this episode, we explore the astonishing life cycle of the mayfly and the massive annual hatch along the lower Susquehanna River, where clouds of insects can grow so dense they shut down bridges and force crews to clear the roadway with snow plows. The transcript traces how these insects spend most of their lives hidden underwater as nymphs, only to emerge in a brief, frantic burst of flight, mating, and egg-laying that has rema...

On June 9, 1906, a quiet riverside community at Shenks Ferry was shattered by one of the deadliest disasters in Lancaster County history. In this episode, we revisit the catastrophic explosion at the McAfee Powder & Oil Company, where a blast inside the factory’s “punch house” instantly killed eleven workers and sent shockwaves across the surrounding countryside. The force of the explosion was so severe that m...

In this episode, we explore the engineering, history, and surprising sophistication of the dugout canoe, especially as it relates to the rocky, fast-moving waterways of the Susquehanna River. The transcript shows how these heavy, durable boats were perfectly adapted to local conditions that would have destroyed lighter craft, and how Indigenous builders created them using fire, shells, and deep practical knowledge of wood, water, a...
