11-Aug-2000 -- We enjoyed finding the 40N 77W
confluence and decided to visit 40N 78W. After leaving Lancaster, PA. we
entered the Pennsylvania Turnpike (oldest in the nation) and headed west
into the Appalachian Mountains.
The turnpike has several tunnels drilled through the mountains. The
Tuscarora Tunnel (photo #2), is a good example. Inside the tunnels, our
GPS receiver lost the satellite signals. After exiting the turnpike at
the Fort Littleton interchange, we headed south on route 522 to locate
the confluence. The aerial photo from the confluence web site, really
helped us to determine which farm road would give us the best access to
the confluence. (Photo #3)
We explained to the land owner that we are earth science teachers
from Manheim Central High School. We also explained the significance of
her property relative to the 40N 78W confluence. She agreed as long as
we would lock the fence to prevent her cows from leaving the field and
make sure we turned on the electric fence when we left the property.
She also warned us about the cow pies and groundhog holes throughout the
fields. Our shoes were clean when we got back into the car.
After jumping a stream and walking up a large hill for about 1/2
mile, we found the site with the GPS receiver. (Photo #6). The
confluence was located in an open field, without trees or corn to
prevent us from standing on the exact location! (Photos #4,5)
The field included clover, Queen Anne's Lace, and residue from our
bovine friends. This view is looking west from the confluence. (Photo
