In Eastern theory, fall is the transition from yang to yin, between the expansive growth phases of spring and summer to the inward, cooler, fall and winter seasons. In this course, we will take five easy hikes around Schenley Park to observe the fall season. We'll notice plants such as lambs-quarter and mullein dropping their seeds. We'll see hawthorn, crabapple, and dogwood trees releasing their fruit, and find other trees such as oak, ginkgo, and black walnut dropping nuts. We'll explore the abundance of fall mushrooms; observe birds - both the migrants and year rounders; watch wildlife; and soak in the colors of the changing leaves. This course will meet rain or shine (except unsafe conditions such as lightening/thunderstorms) and involve walking and hiking on possibly uneven natural paths and surfaces, up to one mile or so each week.
