Though it was made 70 years after the B&O had been excavating rock, even
in the 1890s such cuts were tough work. This one was "the straw that
bankrupted" the Columbia and Maryland Railway owners.
The path can get muddy here, hence the wooden platform / walkway. The
white objects on the hill at left are a fence that appears to mark
the edge of private property.
I'm not sure if the stone seen in the lower right foreground has any
particular significance (i.e. if it is a trolley line artifact).
