Our yearly bicycle field trip exploring Philadelphia’s 500 million years of geologic history is back!

We’ll meet in the garden on the southeast corner of 5th and Chestnut, then ride to the beautiful and scenic banks of the Schuylkill River, and then on to historic Rittenhousetown on Wissahickon Creek. We’ll stop at a number of locations along the way, where our guide, geologist Ray Scheinfeld, will talk about the complex geology of this area as well as the surface water drainage and cultural features that have shaped over 300 years of development. These geologic features presented numerous engineering design, environmental, and construction challenges during Philadelphia’s history and development.

The trip will proceed at a pace of 9-12 miles per hour with frequent stops. The tour will cover a round trip distance of approximately 18 miles and there will be several opportunities to shorten the trip if desired. The terrain is generally level with a few small (<30 feet) gradual elevation changes. The entire trip is on paved streets and bicycle paths.

Participants may bring their own bicycles or may rent bicycles at one of several locations near the start of the trip (list provided on request). Helmets are required for the trip (provided with the bicycle rental or bring your own). No bicycle repair support will be provided during the trip. A refreshing (and much needed!) light lunch when we reach the end of the tour at Rittenhousetown. Trip is limited to 25 participants. Minimum age is 16 years old.
