The Botanical Society of Washington is planning an easy-going field trip for kids, old-timers, and everyone else to the Pierce Mill area of Rock Creek Park (Washington, D.C.) on Saturday November 3rd, 2007, starting at 2:00 p.m.

Rock Creek cuts deeply into the complex Piedmont bedrock here; a geologist may be able to join us to help relate bedrock, landforms, and vegetation. Fall colors should be conspicuous along the easy trails, and kids (and others) will have the chance to study fallen leaves and fruits and match them with nearby trees. We will particularly watch for stands of one familiar tree species, native nearby, which may (or may not) be native in the District itself.

Meet at the NPS Visitor Center at Pierce Mill at 2:00 p.m. By car, from Connecticut Ave., take Tilden St. for ½ mile east (and steeply downhill) to the old mill; Tilden is north of Porter and south of Van Ness and Albemarle. By Metro, exit at Van Ness/UDC, and walk south on Conn. to Tilden, then east down into the Park.
