Mount Davis Observation Tower

The observation tower at Pennsylvania's highest point, Mount Davis.

On our trip back home from Pittsburgh, we decided that an excellent place to stop would be the highest point in Pennsylvania.  I have never been a highpointer, but after my first state high point adventure, I can easily understand how addictive it can be!

The Mount Davis high point is located on a mountain ridge called Negro Mountain.  It is about 4.37 miles from the Pennsylvania / Maryland border, and just over 16.5 miles from the Pennsylvania / Maryland / West Virginia tripoint. My GPS showed the location to be 39.785841°N, 79.176596°W, with an elevation of 3,362 ft.  Which is much more accurate of an elevation than I normally expect from my GPS.  According to the Wikipedia article on the point, the coordinates are 39.786111°N, 79.175833°W.

We saw a few interesting sites on our way to the High Point.  The first of which was the Casselman Wind Power Project. We decided to get out and explore the wind mill area.  I had never been that close to a wind farm before.  It is a really amazing source of power, and it appears to be located in a fairly suitable location, as most of the turbines were turning.

Mount Davis, Elevation 3214 feet, Highest Point in Pennsylvania

We eventually headed back on our journey to the state’s highest point, and headed up the mountain.  The mountain wasn’t very steep at all, and we didn’t even realize we had made it to the top when we passed the high point road sign.

There was a small pull off here, so we got out and took some photos.  There was also a trail going into the woods to a site called Baughman rocks.  We headed back to see what the rocks were all about.  They were pretty cool, and were apparently created by the freeze-thaw cycle which creates similar formations on the mountain.
The climate on the mountain top apparently results in stunted tree growth, the land is of little use to agriculture, and the weather can be brutal.  Somerset County, PA (where Mount Davis is located) claims to be one of the snowiest places in the United States, with over 200 inches of snow each year.  This is attributed to its proximity to both lake effect snows coming from Lake Erie, and Nor’easter storms originating over the Atlantic Ocean.

Next we packed up our car and headed to the high point observation tower.  It provides excellent views of the surrounding countryside, and you can even see a few small towns.  I really would love to come back up in October to see the leaves changing color, it must be an amazing sight.
One thing that stood out to me in photos of the area before I arrived was a particularly tall Pine Tree.  In the photos, it kind of looked like a Cell Phone tower, but upon closer inspection, it actually is a tree.  I have attached the photo of the westward view from the Observation Tower so you can see for yourself.
Topographic map of the area

Topographic map of the area around Mount David

There is a topographic map on the top of the observation tower that gives you a good idea of how the land is laid around you.  There is a good explanation as to why some of the nearby mountains look taller, and how it is just an optical illusion.  This map also notes where different towns are, and you can easily identify them.
Mount Davis is closer to I-68 than it is to I-76, so we took I-68 back to our rendezvous point in Carlisle, PA.

Sideling Hill Gap

Sideling Hill Gap Road Cut

Interstate 68 also had a treat for us.  Interstate 68 traverses Sideling Hill, just as the Pennsylvania turnpike does.  The Pennsylvania turnpike used to tunnel right though Sideling Hill, and the tunnel and roadway are still open to daring bicyclist.  The Pennsylvania turnpike was widened and the tunnel became a major bottleneck.  The route was originally designed for train traffic, so grades were kept to a minimum.  PennDOT determined it would be cheaper to route the highway through a gap in the mountain than to update the tunnel.  PennDot was very lucky that a sufficient gap was nearby that they could use for the highway.  Highway engineers in Maryland were not so lucky with Interstate 68.
The only gap in Sideling Hill in Maryland is at the Potomac River at the West Virginia / Maryland State line.  The engineers decided to make a large road cut instead, and create an artificial mountain gap.  I became interested in road cuts after reading Roadside Geology of Pennsylvania for a geology course I was taking.  Road cuts show the stone formations underneath the mountains, and give you some insight into how the mountain could have been formed.  Seeing the Sideling Hill road cut was an excellent surprise along our trip!
Appalachian Brewing Company

Appalachian Brewing Company

No trip is complete without a stop at a local brew pub.  We stopped at the Appalachian Brewing Company just outside of Camp Hill, PA for some excellent beer, rosemary bread sticks, salad, and peanut butter pie!  The waitress explained to us that they are not located in the borough of Camp Hill because the borough is a dry town.  That is the first I had ever hear of a Pennsylvania municipality being dry!

I got to learn a lot about Pennsylvania on this trip, and am looking forward to highpointing in NJ and DE in the near future.  I also came across an excellent webpage with highpoints for all of Pennsylvania’s 68 counties.  I hope to get to a few of these this summer!
