Hike into geological, architectural, and presidential history at Maryland's lost Seneca Quarry with celebrated guide Garrett Peck.
On this two and a half hour walking tour, we’ll make our way along unpaved trails to view the ruins of Seneca Quarry, notable for producing the distinctive red sandstone used for the Smithsonian Castle and many other DC buildings. It was a focal point in a presidential scandal when the quarry's owners' questionable business practices embroiled President Grant in what became known as the Seneca Stone Ring Scandal.
Our guide for this adventure will be historian and author Garrett Peck. He's been featured on the History Channel, C-SPAN and has presented to institutions across the nation's capital. He recently wrote a book about the Seneca Quarry titled The Smithsonian Castle and the Seneca Quarry.
