The main walkway from the parking lot to Friendship Hill's mansion, which forms part of the site's main loop trail, takes the visitor past a statue of Gallatin doing some surveying.
The mansion, seen here from the front, was undergoing some restoration. The walkway goes past the well and through an archway between parts of the mansion.
Behind the mansion is this gazebo, which overlooks the Monongahela.
The back of the mansion was also undergoing some work.
Gallatin was married twice. His first wife, Sophia, died in October 1789, about five months after their wedding, and was buried somewhere on the estate. According to an unconfirmed story, subsequent owners of the property discovered her remains, and reburied them in a plot surrounded by the low rectangular stone wall shown here. Called "Sophia's Grave", this place is on the main loop trail, about 100 yards from the mansion and the gazebo.
Continuing along the trail, I came upon this pond.
The trail eventually descended toward the Monogahela, via series of steps made out of old railroad ties, and then ran northward along the river, where it came close to a modern railroad. Along the way, I saw these rocks, which looked like they could form a cascade if water were to run down them. This is as close as I got to a waterfall during my entire trip.
I did not hike the entire main loop, but found a cutoff that brought me back to the parking lot, in a direction that took me back uphill. For more on Friendship Hill, go to Grave Addiction.
