Hurricane Ida Storm and 
The Great Freshet of 1869

The September 1, 2021, storm spawned from the remnants of Hurricane Ida was one for the record books not only for the rain it brought to our area, but also for the 16 tornadoes reported around the Delaware Valley. Local news reported that the Schuylkill River is expected to crest at its second highest in recorded history on September 2, 2021 -- surpassed only by flooding in 1869. 

This 1869 event occurred October 2-4 and was known as "The Great Freshet of 1869" and caused death and destruction in PA, NJ, DE, MD, DC, NY, and beyond. For trivia buffs, this is the notorious flood that washed away the Manayunk Bridge. The storm's destruction was reported on the front page of the Philadelphia Inquirer with details neighborhood by neighborhood and state by state.

Maps -- A Snapshot of History


If a photo can say 1,000 words -- how many can a map say? 


Perhaps not as many as a photo? Perhaps a great deal more?


Or maybe maps just say it differently than a photo -- like the weathered old cowboy in the western movie who says it all with a simple grunt. Or maybe like the old cowboy, it is what is NOT SHOWN on the face of a map that tells us far more in the end.


In any case, for map adventurers like me who like to travel historical paths and streets found on these documents, surprises on a map are often exciting. What is found on a map can confirm a theory or ignite an interest to pursue an area of reading/research we'd previously not considered.


In fact, while some maps may lead you to a treasure, I feel a map that introduces a new mystery and propels me off on a fact-finding historical hunt is a treasure in itself.

Consider these map snippets that have surprised folks and the questions they've raised ...


 Historical Maps


Where's the Manayunk Bridge?


Why is there a ferry at the base of the "Wifsahiccon" -- and what's with the spelling?

Why does it say Germantown and not Chestnut Hill?


Library of Congress, Geography and Map Division


Does the map really show positions and lines for defense of Roxborough during the Civil War?

Are those strange marks fortifications in Roxborough?


Were troops stationed here?


Library of Congress, Geography and Map Division


Were there really vineyards along the Wissahickon?

Was "Wissahickon Turnpike" a toll road?

Did it become Forbidden Drive? If so, when?

I invite you to take a few minutes (or if you're like me, a few hours) to check out the digital collection of historical maps that have been assembled to compliment physical map collection in the RMWHS Archive.

Some of the digital maps selected are worn and torn and worse for their years -- just like that old cowboy. Many are as interesting to look at for their weathered features as their hand-drawn content.


Some of the maps are nearly pristine, detailed, and even full of color with buildings, structures, and landmarks all noted. (One of my personal favorites is Gorgas Park drawn by a landscape engineer in 1939. It is a simple map, but graceful in form and worthy of display in my humble opinion).

Some of the maps barely indicate Roxborough, Manayunk, or Wissahickon on them, but each map included in this collection tells a small part of a greater story.

If you're not a map person -- or you are GPS dependent and never held a map in your life -- I beg you to at least look at these images as pieces of art.  You can marvel at the mathematics or magic used to create them long before a plane could fly over or even a hot air balloon could go up and take a peek.

I hope you enjoy the collection. If you find a map you love or want to examine more closely, follow the source link provided with each one. The link will take you directly to it on the Library of Congress or the Free Library of Philadelphia website where you can take advantage of the powerful zoom features. Also, many these maps can also be downloaded from the source institutions in a variety of formats.

Go forth and explore ... and Happy Trails!
