It's back! Our once-a-year, bicycle-based field trip exploring Philadelphia's 500 million years of geologic history, which is all around us yet rarely seen.We'll start in Old City near Independence Hall, 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 guide Ray Scheinfeld will talk about the complex geology of this area as well as the surface water drainage and cultural features that 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 snack will be provided to participants on the return leg of the trip. Trip rain date is Sunday May 23rd. Trip is limited to 25 participants. Minimum age is 16 years old.
