Robert Frost's Stone Wall

Origin
Robert Lee Frost (March 26, 1874 – January 29, 1963) was an American poet. He is highly regarded for his realistic depictions of rural life and his command of American colloquial speech. His work frequently employed settings from rural life in New England in the early twentieth century, using them to examine complex social and philosophical themes.

Effect
This short, stone wall was used to mark the barrier of Robert Frost's Farm. The wall creates an uncrossible barrier, but is incredibly hard to move. The stones, which are stacked in a haphazard way, can be moved to a new location, but they must be in contact with each other to work.
