Other sources define the region as an area extending for 20-30 miles to the east and west of the river. This latter definition would include parts or all of the Kittatinny Valley to the east of Kittatinny Mountain in New Jersey, and westward deep into northeastern Pennsylvania. East of the Shawangunk ridge, in New York are the Town of Greenville and the Town of Minisink, both often included as part of the Minisink region. Their residents attend Minisink Valley Central School District.
