ⓘ Blue Line (New York State)

The Blue Line is the term used in New York state for the boundaries of the Adirondack and Catskill parks, within which can be found the states Forest Preserve. The state constitution requires that any property owned or acquired by the state in those parks "be forever kept as wild forest lands" and prohibits it from selling or transferring them in any way.

It is so called because blue ink was used when they were first drawn on state maps. Began a tradition that persists to this day, although private cartographers also often used green. Although initially they were intended only to guide the future acquisition of Forest preserve land, over time they began to define and have a legal impact on all lands, public and private, in them.
