Geddes Run is a tributary of the Tohickon Creek contained wholly within Plumstead Township, Bucks County, Pennsylvania, in the United States.

History

The first inhabitants of the area of Geddes run were the Lenape people. Many artifacts have been found including 'turtlebacks' fashioned by the Lenape people from a quarry in the area of Geddes Run. The region became part of the Walking Purchase of the family of William Penn in 1737.

The nearby 'bluestone' quarry was operated for many years by Nicholas L. Heaney which supplied thousands of feet of flagstone and curbstone for Doylestown's streets until replaced by concrete.

On 24 August 1891, a storm occurred, which was officially measured in Doylestown at 5.21 inches (13.2 cm) in 24 hours caused Geddes Run to flood resulting in severe damage in Point Pleasant including the destruction of the Solomon Fulmer store and severe damage to the covered bridge over the Tohickon Creek.
