The Spring Hill Farm is a historic slave plantation located in Ellicott City in Howard County, Maryland, United States.

The site south of the Patapsco River produced Native American arrowheads in routine farming.

Garnett's brother James "Booker" Clark maintained his credibility as a revenue officer by destroying the operation.

By the 1970s the farm had been subdivided down to two parcels totaling 11 acres, with a large power-line easement and the New Cut Landfill facility occupying the northern tracts.

In the year 2000, Glen Mar Church purchased 21 acres of the farmland from the Baugher family with an address of 4701 New Cut Road.
