Pennsylvania - a portrait of the keystone state

Discover every corner of Pennsylvania, from the place where the
United States began to the shores of Lake Erie to the first-class city
of Pittsburgh, historic Scranton, and the rural farmland,
forestland, and small towns in between. Visit Pennsylvania's
historic sites, which are also the nation's historic sites because so
many important events took place here. View the birthplace
of the only US president from Pennsylvania, trees over 450 years old,
the place where oil was first discovered, the peaceful Amish
countryside, historic colonial buildings, and modern metropolitan
cities. Through striking images and detailed captions, join the photographer on a journey of one of
the country's most significant and diverse states.
