What is the setting of The Lovely Bones?

Sebold's
novel takes place in 1973, in upstate, rural New York's Stofulz County.  The , Susie Salmon, was
killed on December 6.  Susie  alternates between watching action on Earth from Heaven,
remembering her past on Earth, and adjusting to her new reality as a spirit. 

Most of the descriptions of her home on Earth are
non-distinct, 

But on December 13, 1973, it was snowing and
I took a short-cut through the cornfield back from junior high.  It was dark out because the
days were shorter in winter, and I remember how the broken cornstalks made my walk more
difficult.  The snow was falling lightly, like a flurry of small
hands...".

We learn that the Susie is in New York from
her description of taking a day-trip in which she goes with her class to the Museum of Natural
History. 

Later, in Chapter 4, the news item announcing her murder, we get
the name of the county: 

MISSING, FOUL PLAY SUSPECTED;
ELBOW FOUND BY NEIGHBORING DOG; GIRL, 14, BELIEVED KILLED IN STOLFUZ COUNTY
CORNFIELD.

Sebold probably purposely made her setting on
Earth rather vague because Susie's story could be anyone's story.  It helps the reader identify
with her life and after-life.
