Valley Forge Redux (and Discovered)

Box-elder (Acer negundo) flowers

We took three ambitious walks over the long weekend to firm up after a winter whose exercise consisted largely of upper body work (i.e., snow shoveling). Two of the walks were mostly for sheer movement and exercise, but yesterday we returned to Valley Forge National Historical Park and walked the River Trail that parallels the south shore of the Schuylkill River to see how far spring had advanced since our visit two weeks ago.

Valley Forge is a great place to walk, but ecologically it's a disaster. There's a huge deer herd that's culled only through (numerous) automobile accidents and by hunters when deer unwittingly cross the border of the park onto private land. As a national park, there's no hunting allowed inside the boundary. In addition, the natural habitat is badly fragmented, so the landscape is beset by all the problems inherent in largely unmanaged, fragmented habitat--especially invasive vines and groundcovers. Right now, the scourge of the Eastern floodplains, lesser celandine, is everywhere.

The western half of the 3-mile River Trail follows a narrow course between the Schuylkill River and a formidable (obviously man made) embankment about twenty feet high. I had always assumed on our relatively frequent visits that the embankment was the edge of a huge fill--that the area behind the embankment had been used for a landfill or for clean fill from construction. I'd never really investigated. On this walk, though, I proposed that we take an alternate route back to our starting place (rather than just walk out and back on the same trail as we usually do). We climbed the embankment, thinking it led to the alternate trail I sought--and instead of finding a flat plain on top of fill, we entered another world!

The area behind the embankment wasn't solid landfill as I had suspected--the embankment was a levee, created most likely to prevent flooding from the river and to allow the land behind the levee to be farmed. Over the years, though, the area behind the embankment began to retain water, and now it supports a long series of interconnected forested swamps. It was beautiful and exciting. We walked back on a well-worn but unofficial trail along the forested crest of the levee--the swamps one side and the River Trail and Schuylkill River on the other. We felt like we'd stumbled onto a strange new world.

Following the Water

Often on impulse, I walk out by myself:
Magnificent scenes, I alone know;
Walk to the source of the stream
And sit down to watch the clouds rise.

Wang Wei


Somehow, I missed the fact that David Carroll, author of one of my very favorite books, A Swampwalker's Journal, published a new compendium of essays in 2009, Following the Water: A Hydromancer's Notebook.

Carroll, who won a MacArthur Foundation "genius" award in 2006 for his work as a writer, artist, and naturalist has assembled a series of reflections on the watery natural world near his home in New Hampshire. The essays document Carroll's expeditions into a complex wetland ecosystem, and are arranged to coincide with the seasons. The book's namesake essay is the longest and occupies nearly a quarter of the book; most of the rest are far shorter--sometimes only one or two pages.

The book is intensely personal and introspective, perhaps even more so than Carroll's earlier works. I also found it to be touched by more sadness. His laments about the diminution of the natural world by human activity and population growth are more explicit and disheartening than the asides that he included in previous books. Nevertheless, Carroll writes elegantly and lyrically, and he transported me into the heart of the alder carrs and vernal pools he knows so well. No fan of Carroll's--or any Northeast naturalist--should miss this book.
