The Philadelphia Chapter of the Lewis and Clark Trail Heritage Foundation is dedicated to stimulating public interest in and advancing knowledge of the Expedition as it relates to the Philadelphia area. Members meet quarterly to share specialized interests and to learn about the historical, scientific, social, and cultural significance of the Expedition. The Chapter also conducts field trips to local points of interest related to the Expedition.

The chapter is part of the national organization - the Lewis and Clark Trail Heritage Foundation, Inc. - which convenes each summer, usually at a location along the Trail, to conduct business, hear guest speakers, and visit interesting sites.

Philadelphia hosted the Annual Meeting in August 2003, 200 years after Meriwether Lewis came to the city to study with the mentors Thomas Jefferson recommended and to gather supplies for the Expedition.

CHAPTER MEETING SUNDAY OCTOBER 18, 2015 (rain date October 25)
Tour of Lenape Village
An exciting follow-up to our  January 2015 "Traces of Lenapahoking" program

This will be a hands-on living history experience which will give us an opportunity to travel back in time to the 1500’s to learn firsthand what it was like to live in the Delaware Valley as a Native American just before contact with European settlers. Trained educators dressed in authentic buckskins will show us:

- What kind of medicines the Lenape used and where to find them

- How food was cooked and stored

- What kinds of animals they hunted and uses for all parts of the animal

- How the Lenape made bowls and other artifacts from nature

- How to plant a Three Sisters’ Garden and what foods were foraged

- What kind of houses they lived in and Lenape social structure

- How to make a fire by friction using only natural materials

- How to make rope from natural materials

This experience will be an exciting follow-up to our “Traces of Lenapehoking” program at our January 24th meeting. This program should be very interesting for all ages. Children are welcome!
