Excursions at #fortmiles. Most of these areas around the revetments were clear-cut in 1941 and to camouflage the railway batteries the Army issued careful planting and netting plans. Now they are surrounded by a thick coastal forest. #bunkersnberms #plottingroom #industrialarcheology #militaryarcheology #ticks

Rural Delco upland towns & mill communities linked by a single 7.5 mile filament. Broad Street Station - West Chester, Perryville, Md. on the same strand of modernity wending its way through the sinuous Chester Creek Valley. Brief slabs of shale form deep cuts, gouged out with muscle, steel & dynamite. Now we have a transportationless corridor: a beautifully overengineered slow gradient down and an return. But a museum of 19th century utility. Perhaps one day the trail will link up with the east coast greenway and in the post-fossil eons beyond again become a highway of sorts. #odology #railroadlandscapes #delco #railstotrails

Doing some deep historical background for some #deepecological planning. Hill's 1787/8 map of The District of Southwark, Twps. Of Passyunk & Moyamensing shows a massive cove of tidal marshlands sweeping below the built up portions of Southwark along the Moyamensing ridge and into a broad drainage of the Little Hollander Creek and Hay Creek complex down to Greenwich Point, significant enough to be noted as the #WicacoeMeadows #historicalcartography #ecology #riparianbuffers #marshaccretion #bioengineering #wicaccomeadows #turtles

Trolley Trail Notes. Still very possible to get turned around even in the wilds of upper West Park. Re studying the lay-of-the-land in the Trolley Trail's glades between Belmont and Chamounix Hills (Mt. Prospect)
