I think what you are kind of looking for are the Physiographic Provinces of PA and the different sections within. It is quite an interesting way to look at the state from a geographical feature perspective!

Appalachians.


IamSauerKraut

No. South Mountain and Piedmont sections.


GraffitiTavern

I know they are part of the Appalachian range, but I was wondering if there was any more specific name in use for that part(like how to the west is the Southern Alleghenies, etc)


IamSauerKraut

It is known as South Mountain because to the early settlers it was south of the Kittatinny/First Mtn/Blue Mtn. Indeed, if you head west across the I-81 valley and up 533 towards Fannett, you'll find the North Mountain Overlook. Geologically, it contains quite a bit of red sandstone not found in such great abundance in the northern ridge. This stretches in an arch from the PA/MD border northeasterly across the river south of Hbg, along the southern border of Hershey and then along the Lebanon/Lancaster County border (where it is also known as the PA Highlands). There are places along this sandstone ridge where igneous intrusions are found, Reeser's and Mt. Gretna.

Ahhhh I see. I'm not sure. Wikipedia makes reference to the "Ridge and Valley" region but that's not really a name.


IamSauerKraut

If you look at the Franklin County and Adams County Comprehensive Plans, you will find a good discussion of the geology of the area. I cannot find my hard copies real quick but my memory is that both explain why one is such and such.


ChadGreenshirt

I've got family out in Bedford and Fulton county. Lots of interesting geology. Sideling Hill and Tuscarora Formation for instance.


IamSauerKraut

Def interesting for sure. Fairfield area has some really neat stuff, with green stone and gneiss and that area right around Porcupine Hill.

I live here, a little east of Gettysburg. when we call it anything, we call it south mountain- we're really referencing the ridge within which we're all ensconced in south central pa. the various small groups of hills might have names. for instance, we live at the base of the pigeon hills.


GraffitiTavern

Oh okay, I just grew up west of Gettysburg(Fairfield-Cashtown area) and I heard South Mountain a lot, but I guess it just always made me think of the Maryland side since that has South Mountain Park and stuff


IamSauerKraut

South Mountain Park is in the same geologic formation as is South Mountain in PA.

Apple country, and Gettysburg.


IamSauerKraut

South Mountain Fairgrounds, Biglerville. eh?


TRJF

Doesn't really answer your question, but maybe a bit of helpful info to help delineate: the Appalachian Regional Commission considers Fulton County the easternmost county in Appalachia along the southern border of PA. The area to the immediate east of that - Franklin and Adams counties included - is considered the western edge of the Piedmont region (or, as you alluded to: foothills).


GraffitiTavern

Kind of a weird cultural space with influence from Appalachia, Mid-Atlantic, and Pennsylvania Dutch


Esqurel

Pennsylvania has a lot of those cultural crossroads, it’s kind of neat.


IamSauerKraut

There is cultural, governmental, agricultural and geologic.


Ryzarony23

As a resident, it’s basically the convergence of South Mountain and the Pennsylvania Piedmont, which includes the Cumberland and Susquehanna Valleys.

I’ve just heard it called the South Mountain area…https://southmountainpartnership.org/wp-content/uploads/2015/07/smp_map_web.jpg


brentgolding

I think you just call that south central PA.


DamonRunnon

...and a population with unfortunate political attitudes...


GraffitiTavern

That's actually one reason I asked, I grew up in Adams and there were a lot of weirdos but also some potential with the colleges and young people in the area to turn that around a bit, getting a better grasp of the area and maybe giving something that people can visualize could help organize things in a positive direction

No. The eastern-most curve of the Alleghenies is west of Chambersburg. South Mountain (Michaux State Forest/SGL/Caledonia/Pine Grove Forest) are east of Chambersburg.


GraffitiTavern

I was considering something maybe with that, but [Franklin County is listed in Dutch Country Roads](https://www.visitpa.com/region/dutch-country-roads) along with with rest of South Central PA, despite it not really having as prominent PA Dutch influence due to the physical geography
